I have seen something similar...
I wonder if your card is sending a signal that the TV can't display (80x25 text).
If you have a DVI monitor you can see if the card is actually displaying during
POST (I'm sure it is).
If you switch to VT 1 (ctrl-alt-F1) does that display?
If not then you may want to use the framebuffer console (fbcons) and switch
resolution. My VT's now run at 1920x1280 :)
You will need to alter grub to supply a vga= parameter. It still won't display
POST but you'll see the boot sooner.
(Nb fbcons also lets you run 'splashy' so you can have a pretty bootup sequence
- good for a TV PC.)
