No. That check in sunffb is not changed. Apparently a reboot cured the
original problem; I have heard nothing further on it.

I was prepared to modify the check for the reporter and for the reporter
only: after all, sunffb has been running fine for years, and this looked
like a one-user problem. It seems it was a no-user problem, and sunffb is as it
always has been.

Only recent changes to sunffb are yours for XAA & friends.

By the way, you get that abort from xfree/xorg and sunffb and Elite when,
as here, you do not have the microcode loaded. If you install and load
the afb microcode, that abort should go away. (As, I believe, the bug
reporter indicates.) Someday I might even look at why this is the case.

Hope this is close to on topic,
Regards,
Ferris
