640x480 is normal.

Because fbset is only useful for setting /dev/fb. You want to use stty to set the resolution now. The advantage of this is we don't end up with a console mode of 80 3/4 columns by 30 1/4 rows. Try
stty cols 160 rows 64
assuming you are using 8x16 fonts.

Sounds like a monitor timings issue. fbset cheats by taking times from the /etc/fb.mods file. I'm working on patch that was sent to me to deal with this.

Same problem again. It is a monitor timings issue. We are working on this.
