FYI I have resolved this issue.

I had CONFIG_FRAMEBUFFER_CONSOLE=m

in the kernel config. I think the frambuffer code was working fine (explaining 
the screen blanking during boot), but then the console subsystem 
reconfiguring the display back to text mode.

Changing to CONFIG_FRAMEBUFFER_CONSOLE=y fixed this.

This is obviously a 'gotcha' to remember for the future, but perhaps also a 
candidate for further thought, since all subsequent use of the fb device (for 
graphics) produced a corrupt display.
