There is no fixing the problem, the BP6 put the missing SMP functionality of the Celeron processor into the motherboard's chipset, which causes some strangeness. (at least, that's as far as I understand) I have an identical board and procs, and when I had Linux on it (it has since become the wifey's machine, so it now has .. umm .. that _other_ OS on it), the APIC error seemed to be better or worse with different kernels. I found that the later 2.4.x kernels handled it much better. As far as it spitting out to the console, I seem to remember that that was kernel specific too. Under later kernels, those errors were simply tossed into the kernel log. At which point it was easy to ignore them. You also might want to check and make sure you have the latest BIOS installed.
