| Rik, I saw you had the same experience? Please ACK it :)

with acpi on it can also run, but not if you supply vga=. I tried with
vga=0x317 and it stalls after "Freeing unused kernel memory". When i
turn off acpi using acpi=off and also supply vga=0x317 it continues
booting, but hangs during execution of bootscripts. An example of this
is a script executing /bin/setfont.
The complete append line i use is:

root=/dev/hda3 debug video=mtrr,vesa:1024x768 vga=0x317

I can send my .config and/or dmesg output on demand, but since i am not
the only one with this problem and mcp already send his i did not find
it necessary.

It would be interesting to try reverting probe_roms-02-fixes.patch and
probe_roms-01-move-stuff.patch.

Reverting these two patches does nothing. The result is exactly the same
as above.
Reverting the acpi stuff that went into -bk some days ago does solve the
problem. I haven't checked yet which part to be exact causes this though.
