Fine. Second reason might be that the ExtInt pin is wrong for the APIC. I mean 
it is set wrongly. To which pin sets the original BIOS the ExtInt IRQ?

You arent, its important to ask!

#isadump  -f 0x4d0

you should see the two bytes decoding at 0x4d0 and 0x4d1.

bit0 at 0x4d0 is IRQ0, bit7 is IRQ7

0 is level
1 is edge

This is set by linux.
