I have GeForce 8600m GT on Acer ASPIRE 5920G laptop and have the identical problem. (low resolution with nouveau, black screen with nvidia-173 and only command line with nvidia-current (260)).
The same laptop with the same card works perfectly with Lucid using nvidia-current (195?) driver.
I can confirm this bug.
