I applied the patch. It makes my monitor turn off in all four
modes. If I remove the patch, all works again. My ViRGE is a
revision 6 (86C325), just like yours. Things that may differ 
is that I use the Goldstar 56i monitor and that I insmod the
driver with the following script:

for i in /lib/modules/2.2.4/video/*; do insmod $i; done
#insmod /home/niklas/arkiv/degas/degas/kgicon/kgi/kgicon.o
insmod /home/niklas/arkiv/degas/degas/kgicon/kgi/kgicon.o kgicon_width=800 kgicon_height=600 kgicon_bpp=8
