I see.  It seems tht all that we need is calling it from bottom half.
Then, we don't need to introduce our own task queue and bottom half
handler (I'm afraid of conflict of SERIAL_BH with standard serial
driver).  We can use IMMEDIATE_BH instead.  I've committed
IMMEDIATE_BH version.  Please check CVS repository.

Besides, I've installed your 7707 and semaphore fix.  Thanks a lot.
