Neither appears to help.

80x25 text mode is fine (either with VT switch, or after X exists.)

Yes.

Attempting to describe more, since 'blinking' is a bit of a shorthand:

- The display starts (mouse cursor on black). The cursor wobbles a bit (out of
sync?), and there are some minor display artifiacts.
- The display flashes on and off a couple of times (when it's on, it's still
wobbling with slight artifacts)
- The 'on' flashes decrease in frequency, to a point after about 30 seconds
where the display's just blank.
