Hmmm... some output is missing from the vanilla Linux 2.4 log, because
the console logging level isn't including debug messages.

To be specific: there should be a dump of IO-APIC content between the
lines --
 testing the IO APIC.......................
 .................................... done.

'dmesg -n 9' may get you these messages, or changing
kernel/printk.c:DEFAULT_CONSOLE_LOGLEVEL to 9. If none of this helps,
edit include/linux/kernel.h and change the definition of KERN_DEBUG to
the same as KERN_ALERT ("<1>").
