I hacked input-kbd to ignore the map->size calculated above
when writing a new map.. seems to work. Weird that the old
method stopped working with 2.6.36, though.
I'm using this with ir-kbd-i2c.c as the hardware driver
for the hauppauge R/C interface on a PVR-250 card.
Hey.. perhaps you may also know where in the code this thing
is being forced to a repeat rate of about 4 times/sec max?
I'd like the remote to be slightly faster that this,
but my 2.5.35 (and earlier) hacks to ir-kbd-i2c now don't
work for repeat intervals less than approx 220msecs.
Cheers!
