Hum...
Could you make a diff of the source of those two version of
the smc driver ? Don't forget to also do a diff of irport.c.
As far as I remember, only trivial change to the smc driver
went in. The patch was included around 2.4.10 and is attached
below. You may want to "undo" the patch to see if it helps.
Other solution is that it's not SMC specific. In that case,
please send us an irdadump of the failure.

Jean
