As a workaround you can hit space several times starting when you see the
5 second countdown to enter the monitor.

I have never noticed this problem.  I have the latest BIOS and I am running
-current.  So it might be a 1.6.1 issue.  Oh, I am running at 9600bps also.

My ethernet works great.  This may be a result of the "short cable" patch
that wasn't committed until recently.  I don't believe it made it to 1.6.1.
You can use cvsweb to diff 1.77 and 1.78 of if_sip.c.

Get rid of the card. :)  My 'SunDisk SDCFB-16' works fine.  I can't remember
if I tested my 64MB and 128MB cards.  My 16MB card is a bit tight on space
so I might be using one of the larger ones before too long.

Sounds cool.  Are you willing to send-pr it?
