Glad to hear that!

I am not sure, I've never tried to hook up additional
lines.  I do have an 8-port MDP somewhere, I'll look
for it here shortly, and see if I can hook it up.

Just what I have added into the driver.  If there is 
something that we are obviously missing, I can go back
and reference the HP-UX mux driver and see what is
missing.

Please! :)  I do not use multiple lines currently ...
I only use the line 0, so any testing, optimizing, etc
is greatly appreciated!

I have it on my local system.  It is _very_ ugly at this
point.  I have got enough to query information from the 
spifi chip, register an interrupt, etc... but currently
I can not get the spifi chip to actually generate an
interrupt.

I would be happy to send you a copy when I get back next
monday (unless you catch my in the next hour or so), but
I'm not ready to check it into CVS yeah until I get rid
of the some ugly hardcoded hacks, global variables, etc.
Right now the driver is really coded to gather info from
the ESIEE E35 that I have been testing on.  Once again,
I do not have any docs on the chipset, I am using both
the NetBSD and HP-UX drivers as reference. :(

The driver should be easy to modify for your specific E55,
but not sure if you are interested in that level of work,
messyness now.  I promise it will get much better :)

Thanks,

- Ryan
