I've just tried a stock 2.6.11 fresh from the tarball, and I see some of what
you are seeing.

I don't see any problems with text colour or images. Text is white, Tux is 100%
normal. This on a single processor K6/2-450 with a Creative Graphics Blaster
Exxtreme, BTW.

However, I do see the problem switching back to a vt from X. In fact it does
work, except that the video is blanked. This is a bug in pm2fb.c exposed by
recent changes to fbcon. Please try this fix (works for me) and let me know if
it restores normal service for you too.

Returning to your problems with text colour and images, can you try
with CONFIG_FB_PM2_FIFO_DISCONNECT=n and see if that makes a difference.

Thanks.
