My card supports I2C, this is my test monitor not supporting it (my real
display does). But I think the slow loading can be solved using the
bit_test=1 parameter for i2c-algo-bit. I did not tested yet, but it
works for i2c-matroxfb, so I'd expect it to work for rivatv too.

BTW I'd like to report a bug. If I load rivatv or any related module
while in the console, my system deadlocks. I have to reboot it the hard
way. The same operations made under X work OK. Any clue?
