recent nvidia-driver trouble

Hi,

Sometime during the last week i have started to encounter trouble with
my system locking up trying to switch from X to console, but only when
using the nvidia-driver kernel module. Using the plain "nv" driver works
without any problems ... When the lock up happens the system seems to no
longer respond to keyboard input etc. (haven't been able to confirm
wether or not remote access is still possible).

Is anybody else experiencing similar problems out there ... this has
used to work for months without problems ... i made sure to force a
reinstall of the nvidia-driver port on every new kernel install but that
just doesn't seem to solve the problem either.
