Marcel,

The following patch does two things:

- Adds support for setting the baud rate on the STLC2500.
- Adds another optional argument to hciattach for use with stlc2500/bgb2xx 
devices that require initialization of the bdaddr.  Basically if you specify 
this option on the command line, the address specified will be used during 
stlc2500/bgb2xx initialization.  Otherwise a default will be used.  The 
manpage has been updated as well.

Let me know if there are any issues!
