Just another data point related to r262226:
Yesterday, I upgraded a stable/8 system from r260539 to r264426, which coul=
d not =
finish booting. In my case, it stopped just after detecting an agp card (an=
d =
could boot if agp was disabled by device.hints).
Reverting r262226 gave me back a fully usable system.
This system is also a Dell, but a (oldish) Dimension 4550 BIOS A08.

I think so, if jhb (cced) keep being interested in stable/8..
BTW, this morning I succeeded in booting a stable/10 snapshot r264194 USB s=

on this machine.
