Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+/*
+ * Belkin is selling a dongle called the SmartBeam.
+ * In fact, there is two hardware version of this dongle, of course with
+ * the same name and looking the exactly same (grrr...).
+ * I guess that I've got the old one, because inside I don't have
+ * a jumper for IrDA/ASK...
+ *
+ * As far as I can make it from info on their web site, the old dongle 
+ * support only 9600 b/s, which make our life much simpler as far as
+ * the driver is concerned, but you might not like it very much ;-)
+ * The new SmartBeam does 115 kb/s, and I've not tested it...
+ *
+ * Belkin claim that the correct driver for the old dongle (in Windows)
+ * is the generic Parallax 9500a driver, but the Linux LiteLink driver
+ * fails for me (probably because Linux-IrDA doesn't rate fallback),
+ * so I created this really dumb driver...
+ *
+ * In fact, this driver doesn't do much. The only thing it does is to
+ * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
+ * driver is called "old_belkin" so that when the new SmartBeam is supported
+ * its driver can be called "belkin" instead of "new_belkin".
+ *
+ * Note : this driver was written without any info/help from Belkin,
+ * so a lot of info here might be totally wrong. Blame me ;-)
