APIC and "ISA" interrupts.

After upgrading our fileserver to 2.4, I can't seem to get the ISDN
card to work. I think that's because the kernel is using the APIC to
route interrupts, such that my BIOS configuration "used-by-Legacy-ISA"
is no longer in effect.

I tried disabling the APIC with the following results:

Local APIC disabled by BIOS -- reenabling.
Found and enabled local APIC!
Kernel command line: auto BOOT_IMAGE=linux ro root=302 BOOT_FILE=/boot/vmlinuz disableapic

as far as I can see, the code to print "local apci disabled by bios"
is not called if "disableapic" is on the commandline.

This is linux-2.4.10 that I got with SuSE 7.3

Roger.
