This kernel is designed for use in a vmware client only ... it is not
for using on the host.

The purpose of this kernel is to solve issues with the kernel timer by
setting the the timer from 1000HZ or 250HZ to 100HZ.  You would not want
to do this on the host ... only on the client.  It is to fix this problem:

Using a standard kernel on the host is much better than using this
kernel ... and the standard kernels have PAE support for the host.
