I'm trying to use vmware on a current machine compiled from source updated
February 17th, 2002.  It works fine until I connect the CDROM drive, and
then I have problems.  (fine in this case is a few second pauses every
so often, but mostly usable.)  The problem is that with the CDROM connected,
 about every 2.5 seconds, the vmware process hangs for 2.45 seconds.  This
makes it difficult to use, and installing software from CDROM impressively
fun.

Is there anything I can do to make this usable with the CDROM drive?  I've
used another machine to build my vmware images in the past, but right now
vmware causes that machine to panic, uvm_fault, fatal page fault in
supervisor mode, so using it is out of the question (cvs updated Feb 24th).

Choice bits from vmware's log:
