[Peter Jay Salzman <p@belial.ucdavis.edu>]

dear all,

when i try to run test3Dfx on my dual celery550 (debian 2.2, kernel
2.4.0-test9), it reports:

	test00:
	Clear screen to blue
	2.60.00.0415
	Resolution: 640x480
	Press A Key To Begin Test.
	gd error (glide): Can't find or access Banshee/V3 board
	gd error (glide): grSstSelect:  non-existent SSTSegmentation fault

i insmoded 3dfx.o:

	% lsmod
	Module                  Size  Used by
	3dfx                    4920  -4 (unused)

and have the relevant deb's installed (i think):

	% dpkg -l "device*"
	un device3dfx-mod <none>         (no description available)
	ii device3dfx-mod 2.3.4-2+custom Device driver source for 3Dfx boards for 2.x
	un device3dfx-mod <none>         (no description available)
	ii device3dfx-sou 2.3.4-2        Device driver source for 3Dfx boar

and installed the dpkg:

	# dpkg -i device3dfx-module-2.4.0-test9_2.3.4-2+custom_i386.deb 
	Preparing to replace device3dfx-module-2.4.0-test9 2.3.4-2+custom (using

	# dpkg -l "*glide*"
