I have successfully used the cirrus54.grn driver with a Cirrus card,
and it works fine. I am primarily using it in the 1024x768x256 color mode.
The .GRN extension refers to the newer graphics drivers that work with
the LIBGRX graphics routines. They allow you to specify the number of
colors (e.g., nc 256) in the GO32 environmental variable.

BTW, if anyone is interested, I hacked the OAK.GRD driver to support
Oak cards with 1M, so that they will go into the 1024x768x256 color mode.
It was a trivial modification, but I'd be glad to upload it if it saves
anyone some time and effort.
