That's not the only fbdev bug in X.  I have been getting a lot of reports
which indicate that FBDev X does not turn off text mode acceleration when
it wants to switch into graphics mode.

As far as I know, the Debian people looking after the ARM FBDev package
haven't produced a patch for XFree for this particular problem yet.
However, it'd be nice to get it fixed by some means.
