I'm using a #9 Motion 771 video card (PCI) 
> vga0: <S3 968 graphics accelerator> rev 0x00 int a irq 10 on pci0.11.0
so I am not sure that would be causing this problem.  But then again I
don't know.  I am going to try moving to int 3, after disabling the 
serial ports, and see if it works better.  It will get me off the 
cascaded 8259 and the broken vga interrupt hack, if that's what it is.
