Because software patches/workarounds are cheaper than producing tested
quality hardware in the first place, I suppose...
And people love to buy cheap stuff, and seem to have a huge amount of
patience with crappy hardware. (Or they just got so used to crashes
and bugs that they think it's normal.)
Did I ever mention that I hate computers? ;-)

Some newer AMD boards are reported to only work when apic (not acpi) is
enabled. And there is no kernel option to re-enable apic once it has
been disabled in the lilo.conf or syslinux.cfg.
