[PATCH] viafb: Don't accelerate blit of color images

[Daniel Drake]

When the Tux boot logo is enabled, the boot penguin does not get rendered
correctly and under certain circumstances the system will hang.

This appears to be because the accelerated blitting code only supports
mono images at the moment, as suggested by a high bit 8 of the GECMD in
viafb_imageblit().
