Comment:
The hang was actually in the viafb code, it was just difficult to debug
with printk's because when the console sem is held, no messages get
printed until it is released. The hang occurred with the sem held.
The issue seems to be that we were trying to render the color boot logo
using a codepath for accelerated rendering of mono images. This was
confusing things. Should be fixed in olpc-2.6.30 kernel branch.
