The problem seems to be that Diamond uses a proprietary programmable clock
circuit in their cards and isn't releasing the programming information.  My
impression is that this is independent of what accelerator chip they use.
You can proabably get a more informed answer by following the discussions
which have appeared in comp.os.linux and comp.windows.x.i386unix.  Before
buying a graphics accelerator for use with unix/X, it would be a good idea
to get the current list of cards and chipsets for which there are Xfree386
drivers.
