 Well, as a test to make sure it all worked, I did it from scratch myself.
What i did was -

 - download and create the floppy from main plan9 site

 - modified vgadb on the floppy to add entry for my nvidia video card.
   There was already an entry for nvidia cards (though it doesnt
   seem to have been built in the kernel yet), so I just added the entry
   for my card

diff /tmp/vgadb vgadb
300a301
> 	0xC0072="Diamond Viper V550"			# NVIDIA TNT

The nvidia section now looks like

ctlr
	0xC00A2="NVIDIA TNT2 Model 64 BIOS V2.05.13 "	# NVIDIA TNT Model 64
	0xC0072="Diamond Viper V550"			# NVIDIA TNT
	link=vga
	ctlr=nvidia linear=1
	hwgc=nvidiahwgc


 - downloaded 9pcflop.gz from
   http://members.optusnet.com.au/~nwaples/binaries/ , and replaced the
   one on the boot floppy with this.


 After this it all worked for me.

 The error message you saw,

sequencer->enter on
sequencer->leave on
dbctlr: unknown controller "nvidia" ctlr

 would happen if the driver wasnt built into the kernel. That shouldnt
happen with the kernel I built.
 I even uploaded the floppy image I used (nvidia.9fd) if you still cant
get it to work.
