I have 2 SMP-Boards and both need noapic. One is from 2001 (AUSUS CUR-DLS),

There are many reasons:
1. Bugs which have such a simple workaround don't get much attention.
2. Usually SMP boards are used for machines, which just HAVE to work,
since they have been expensive. These are not consumer boards.
3. I usually had only USB problems (no IRQ), if ommiting noapic.
USB technology is a cosumer grade technology and enterprise
grade developers don't have much interest in it (until now?).
4. IRQ routing setup is often a BIOS issue. You might be able
to fix that by upgrading your BIOS. That often needs a Windows
tool. Linux people not always (want to) have access to Windows :-)
I reported the all the problems (starting 2001), no developer
seemed interested.
I can report them against the latest RC6 kernel tomorrow and put them
into bugzilla, if we now REALLY care.
