MP-BIOS bug: 8254 timer not connected to IO-APIC

[j0rg3@arribatel.com]

Is there any patch or workarounds about this bug on 2.6.x kernel? I 
already googled this, there are patches on 2.4.x kernel but i dont like 
downgrading the kernel. Or if someone already did a kernel 
tweaking/hacking about these issues it would help.

NOTE: I don't think that there are bugs/problems on the BIOS because 
this box has been already tested and runs smoothly without any problems 
and issues on FreeBSD 6.1
