boot problems pre11 + O(1) H1 & H4 on UP athlon

[Taco IJsselmuiden]

Hi,

i'm having problems booting 2.5.2-pre11 with O(1) H1 or H4 patch.
the last few lines are:

<snip>
POSIX conformance testing by UNIFIX
mtrr: v1.40 (20010327) Richard Gooch ([e-mail])
mtrr: detected mtrr type: Intel
PCI: PCI BIOS revision 2.10 entry at 0xfb470, last bus=1
PCI: Using configuration type 1
PCI: Probing PCI hardware
Unknown bridge resource 0: assuming transparent
Linux NET4.0 for Linux 2.4
Based upon Swansea University Computer Society NET3.039
apm: BIOS version 1.2 Flags 0x07 (Driver version 1.15)
Starting kswapd

and then it doesn't respond to anything (like keyboard leds...)
no oops no nothing ;((

pre11 boots fine without the patch.
even pre10 + G1 boots fine...
