Can you please keep CONFIG_HIGH_RES_TIMERS and CONFIG_NOHZ and try the
following combinations on the kernel command line:

1) highres=off nohz=off (should be the same as your working config)
2) highres=off
3) nohz=off

I tested this with my 2.6.22-rc3 kernel, here are the results:

without any special boot parameters: problem does appear
highres=off nohz=off: problem does not appear
highres=off: problem does not appear
nohz=off: problem does appear

Is there any other strange behavior of the high res enabled kernel than
the b44 problem ?

I additionally built my 2.6.22-rc2-mm1 kernel without High Resolution Timer, 
but the high ping problem is still there.

Hmm, that's mysterious. Wild guess is that highres exposes the hidden
"feature" in a different way than rc2-mm1 does.
