A good example of this is following crash:
https://launchpad.net/distros/ubuntu/+source/xserver-xorg...

ATI driver crashed trying to probe something that didn't exist on ISA
bus after finding the correct card from PCI bus. I think the problem
is the drivers, not the X server itself.

No, he was talking about how the code in hw/xfree86/os-support/bus/Pci.c and hw/xfree86/os-support/linux/lnx_pci.c walks the tree (it's really bad, and only very recently got better). The ATI situation is due to the driver being braindead (use Driver "radeon", not Driver "ati"), and has nothing to do with the code Dave is talking about.

(For what it's worth, I fixed the library-stat()ing in Ubuntu quite a while ago, but the patch only got half-merged into upstream because it broke a couple of things. But I fixed it again in Dave's talk, after realising that it was still sucking.)
