Beginnings of a VMware graphics driver

People,

As discussed in the freak wave of discussion yesterday, here is a
preliminary VMware graphics driver.

It cannot be tested until the fifo commands are implemented, thus, bugs
may be present.  I am having trouble making these functions.  A (very)
brief description would be the fifo is a region of memory through which
pointers cycle through.

It is attached to this email as vmware.lisp.

One of the clearest reference codebases is the Syllable VMware graphics
driver.  You can find this at
http://syllable.cvs.sourceforge.net/syllable/syllable/system/sys/appserver/appserver/drivers/video/vmware/

Comments / suggestions / improvements very welcome.

Thanks,
Martin
