Uhm, I don't really understand what's going on. Also I haven't found anything 
about NO_MIXED_MODE but I made the usual kernel (-current from Nov.09, 
without the spurious patch) with "device apic" and "options NO_MIXED_MODE".
Now quake2forge compiled successfully (which also crashed the machine with the 
last apic kernel) also OpenOffice compiles fine.
I see one difference in dmesg:
Timecounter shows now "ACPI-fast" like with a previous SMP-kernel instead of 
"ACPI-safe" like wth the UP kernel. Just for info attached the new dmesg.


Do you have any enlightning link for me about apic and NO_MIXED_MODE?

Thanks a lot,
