Yes it is.

Well, when doing 'echo 0 > /sys/class/graphics/fbcon/rotate_all' for 2.6.33
I've got the same problem but the lines are vertical. However 2.6.24 seems to
work in non rotated mode.

As far as I can test in rotated mode it happens for kernels from 2.6.24 to
2.6.33 (I haven't older kernel than 2.6.24 that boots on spitz).
