Not this problem (well didn't try those options), but
the Nvidia driver causes my ttyv's to fail miserably:
any switch to a ttyv will cause the system to freeze,
which means that I can't even shutdown properly since
the system goes to ttyv first when doing a shutdown
from KDE/kdm. Games run fine though.

After all, the Nvidia driver is still beta, so problems
can be expected.

I also have Nvidia AGP. FreeBSD AGP didn't change anything
for me with my ttyv problem. I'll try another resolution
(already tried colordepth). Have a look at 
http://www.soulwax.net/nvidia/faq.shtml ,
I found this an excellent FAQ.
