How old is your CRT monitor?
You're changing the frequency (console vs X) that your monitor needs
to scan.
Some Electronic Possibilities:
Your fly-back transformer may be unhappy at the lower frequency
used by the console mode. It's part of a tuned circuit. Some monitors
have some switching going on to change windings used on the fly-back
for different scan modes.
OR
A component on your CRT controller board may be
starting to go. Again this can be related to switching
scan rates in the circuit.
OR
You may need to blow the dust out of the guts of your monitor
What are the scan rates in console mode as compared to your X settings?
Do you see the same flicker in X if you set up an X Session with the
same scan rates as your console mode? (..really low res)
