Resuming after suspension on WinXP doesn't work all that reliably either, especially in the video area, even though the people who wrote the modules presumably had access to all the available card specs.

Regarding the issue with virtual consoles and video cards with lots of RAM - 1 GB of video ram *is* a power user who could be expected to afford a few dollars extra for a few GB more of swap space, so it seems to me that the preferred approach would be to treat the video memory as a special part of the virtual memory system that gets pre-paged to swap at a very low priority and perhaps with some built in latency - in that case there would usually be little extra delay when switching.

Even cheap comnsumercards (starting at 46 Euro here in Austria) ship with 256MB RAM and more and this will only rise. So maybe 1GB is a poweruser now, but in one or two years it could be pretty much standard. And even 256MB is something to worry about.
