Comment 4 for bug 158202

Colin, yes this sounds muchly like bug 127008 (install from alternate CD + issue during configuration of xserver-xorg). In fact I anticipated this might occur:

"One thing I've wondered is other laptops with different gfx chipsets may be experiencing problems like these (but with different symptoms.) So, it'd be good to keep an eye out for any bugs that are occurring for non-intel laptops doing the alternate text install and appearing late in the install process; we could expand this patch to include those cases as well."

I suspect this may be one of those cases.

Mike Chapman, can you please attach the output of `lspci -vvnn`? I'll use review this to determine your graphics chipset, and adjust xresprobe to also apply our fix for it.

Of course, for Hardy, it's likely we'll end up dropping use of xresprobe entirely, thus making this issue irrelevant, but I'd still like to ensure we have everything to fix the bug even if we don't drop xresprobe, for completeness' sake.
