Bug#800005: fbset gets 'ioctl FBIOPUT_VSCREENINFO: Invalid argument'

[Rick Thomas <rbthomas55@pobox.com>]

Package: fbset
Version: 2.1-28
Severity: grave
Justification: renders package unusable

Dear Maintainer,

Prior to Jessie, I could use "fbset" toset the screen resolution on my PowerPC Macs.
This was often necessary if the system happened to mis-guess the actual screen
resolution, or the screen was on a KVM switch.

But now, with Jessie, when fbset is used this way does one of two things,
neither of them useful:
    1) It complains that the resolution is not in /etc/fb.modes so is "Unknown".
    2) If the resolution is actually present in /etc/fb.modes, it says
         ioctl FBIOPUT_VSCREENINFO: Invalid argument
In either case it does not change the screen resolution.

The bug may not be in fbset, of course.  It may be in the kernel.
