Update: I backed out xorg-edgers from my machine. Non-edgers driver does
indeed work without KMS, and acpi=off seems to stop the freezes.
nomodeset has no apparent effect.

Summary:
-freezes with nomodeset
-does _not_ freeze with acpi=off

Problems with acpi=off:
-no sound
-no wifi
-no power management
-possible other irq-related problems (since acpi is used to configure the hardware interrupts nowadays)

I tested with current distribution kernel (2.6.31-15 I think), but
mainline kernel seems to behave more or less the same in this regard.

Note: additional tests by Andrea could actually be of interest, since he
runs the same hardware (Asus M2400N). My device has upgraded wifi
(ipw2200), but that should not matter.

BTW I have to concur with Andreas opinion: the fact that the current
Intel drivers have such severe problems on older hardware and no
developer ever seemed to deem it necessary to maintain stable support
for existing machines is quite upsetting. I have currently only two
options: to either downgrade to Hardy (at least until support is
dropped) or to throw away perfectly good hardware. Or is there a
possibility to disable the HAL detection of the graphics hardware, thus
forcing the machine to vesa graphics or something? That would be at
least a little help (I don't exactly need hardware acceleration on that
machine).
