[PATCH] Resurrect ISICOM serial

The isicom driver had bitrotted badly and although it had some 2.6
cleanup work didn't actually do anything useful.  ISIcom had their own
2.4 driver which didn't work with 2.6 either but had done the hard work
like the locking rewrites.  So I nailed them together and then fixed
some obvious bugs in the ISIcom driver version.
