It sounds like the ARM Debian people still haven't fixed this X bug.
When the X server starts up, it switches the console to _graphics_
mode, but leaves _text_ acceleration on. One of the text
acceleration optimisations is to allow vertical panning of the
display. In order for vertical panning to work, we must have a
virtual vertical resolution greater than the displayed vertical
resolution.
Therefore, whenever text mode acceleration is turned on, the kernel
will always calculate the largest virtual vertical resolution that
will fit in VRAM for your chosen _text_ mode.
Without this optimisation, the RiscPC console will be extremely slow
to the point where it is _unusable_ since screen scrolling will be
performed by manually copying the complete framebuffer within the
VRAM.

No. I'm just surprised that the Debian people who have known about
this for around a year have done nothing to get it fixed.
