Hrm. That certainly shouldn't be the case... You did unload the
lirc_serial module before that, right? What you should be seeing (in
dmesg) is:
lirc_serial: Manually using active high receiver

The output from modprobe isn't what's interesting, its the stuff that
gets spewed into dmesg afterwards when trying to use it. :)

Hrm... That's not looking particularly good... I may have vague
recollections of Janne saying that was known to be busted though, even
when the receiver is working properly. I really do need to dive into
lirc_serial code again, but its... grotty...
For the record, what kernel version is this with? Need to compare the
lirc_serial code in it w/current cvs and git trees...
