+Ugly hack that prevents server termination with xf86-video-fbdev-0.4.1
+(and probably other) while returning from chvt or resume on some
+hardware (e. g. zaurus).
+
+Correct fix would require debugging of fbdev mode during LeaveVT and
+EnterVT.
+
+This patch may cause staying in incorrect or corrupted display mode
+after EnterVT, but on man affected devices it does not cause any visible
+problems.
+
+Hacked code is never called on properly written drivers.
+
+Devices affected and testers involved for future patch removal:
+Sharp Zaurus (spitz/akita): Stanislav Brabec <utx at penguin.cz>

+https://bugzilla.redhat.com/show_bug.cgi?id=238451

+The bug (first line indicates that your device is affected):
+
+(EE) FBDEV(0): FBIOPUT_VSCREENINFO succeeded but modified mode
+
+Fatal server error:
+EnterVT failed for screen 0
