Well http://compton.nu/2009/12/per-packet-load-balancing-with-... explains how I bonded four ADSL links with the same ISP.
We're bonding two fibre to the cabinet lines instead now, which use PPPoE and makes things a bit simpler as they are terminated with pppd on the linux box where they can be bonded with teql.
In fact the BT Wholesale ADSL platform does support PPPoE but most ISPs don't tell you that... I did have my line at home running that way for a short while though, in preparation for upgrading it to fibre to the cabinet.

Thank you for that link. I hope nobody minds the thread-hijacking to ask a little more about this - it's not a topic that seems to have much Google juice.
With that setup, do I understand correctly that - assuming the ISP has the bonding set up on their end - configuring the TEQL interface as you have will work regardless of the connection method used? It looks like it's actually very simple so long as you know the secret sauce.
What I'm not sure about is the IP addresses on the routers. You say that they need to support two different *LAN* addresses; how are the WAN ports configured? Are they bridged or do they need an additional address?
Say for the sake of example that you have a /29 netblock, giving you 6 addresses once you've accounted for the network and broadcast addresses. You use one that's shared between the routers and one for the teql0 interface, leaving 4 available for other machines. Is that correct?
Incidentally, would you recommend the Zyxel P-660 series? I do wonder if a better modem/router might solve my periodic loss of ADSL synchronisation, and while I've tried two different models, it's entirely plausible that they're both fairly intolerant of noisy lines.

Those routers allow the LAN interface to be given up to two aliases in addition to their primary address.
So what I did was to set the primary address to a unique RFC1918 address, which was just used for management purposes when I needed to telnet to a specific router, and then to set the alias on each router to the same, shared, public address.
I then added static routes on each router to pass traffic for our public IPs back to the linux box where the bonding was done.
The WAN ports were configured with separate public addresses - a unique one for each router.
Bridge mode wasn't used - they were acting as normal routers.
I wouldn't like to say if the P660 is particularly good or bad - they were the free routers our ISP provided with the lines.

Interesting, so this sounds like a different configuration than some bonding setups which appear to require only a single public IP address. I wonder if that's down to how the ISP configures their interfaces.
I suspect I could make a lot more progress here if experimentation didn't mean scheduling connection downtime of an unknown duration, which in practice means being physically present in a locked office building in the dead of night (for which honestly they Do Not Pay Me Enough™).
At any rate, thanks for the information.

The question really is, will any respondents to this question be using any ISP *other* than AAISP? They really do seem to be the only people who've tried to make line bonding work in any meaningful way, in the UK at least.

Entanet also offer a bonded option, and they're one of the wholesalers used by UKFSN.
