All VGA cards that I know of are the same in this regard.

If you wait a month or so the next release of Flash Graphics for Zortech
C/C++ will use direct writes to the registers with fg_setpalette() (the 
SCO UNIX version already does).

Other than that you can get any one of various technical reference manuals
from the graphics board vendors.  Call up tech support and ask for a
technical reference manual.  Cost is from free to $50.00 (that was several
years ago -- the same vendor last year was asking $10.00).  I have manuals
for ATI, Video 7 (Headland Technology), Trident, Genoa, etc.  My preference
is for the Video 7 manuals but that could be just because that was the first
one I got.
