Accelerometers jerky with new stable kernels?

Hi,

I get huge "stalls" with accelerometers if using the current kernel in
testing or self-compiled stable branch kernel. Eg. in accelgame or
opendoom, the fps is ca. 1-3, sometimes a few frame rapidly in
succession and then 1 second of stalling. Anyone else experiencing the
problem, possibly with a cure?

During the weekend I tried one self-compiled kernel with all the
"lis302dl" starting patches from
http://git.openmoko.org/?p=kernel.git;a=shortlog;h=stable reverted,
but it didn't help at all. Any idea which patch would be causing the
problem?

Okay, while writing this I noticed I didn't revert
"fix-lid302dl-bitbang-all-the-way-baby.patch", so it might be it, but
I'd like to hear from others and also if it's a known problem to be
fixed.

-Timo, wants the accelerometers back (without losing other goodies in
recent stable kernel)
