I'm glad to hear that classzone works with VMware again (I had report
that classzone-25 and laters do not work).

VMware works with 2.3.99-pre9.1 if you have UP without IOAPIC. If you have
SMP and/or IOAPIC, vmware bombs out because of during reading of
HW IRQ vectors from IOAPIC it finds that HW vector 0x01 is mapped to 0x39
and 0x39 is marked as 'reserved' in Linux VMware build :-( Unneeded safety
check :-(
