Comment(by TimoJyrinki):

 Hi. I tested Andy's kernel (compiled myself) briefly yesterday evening,
 and there was a visible improvement in speed. Unfortunately I couldn't
 charge my Neo while using the kernel (modules should also be rebuild, or a
 bug?), so I went back.

 Could the two glamo patches be put to stable kernel show that it would
 show up on regular updates?

 Anyway, the speed was not that great still, though better, and I wonder if
 the mdelay(100) mentioned here is now the main culprit for rather low
 frames per second everywhere? Eg. scrolling a long contacts list or simply
 playing Numpty Physics. 90MHz clock for core/memory should definitely
 somehow be able to update ca. 480x480 area (eg. contacts list main area)
