Ah.  We'll try that.  But I still hope there will be a real solution to
this (the Soekris boxen are spread over a large area and we only have
remote access to them>.

We're using 38400 bps and 1.6.1.  But 1.6.1 works Just Fine on other pc
hardware (well, that doesn't prove anything..).

Sami patched the 1.6.1 driver (imported the changes from -current), but
we are still seeing problems.  Part of the problems _may_ be caused by
Realtek cards (although they have been working fine on my machines before,
AFAICT).  We haven't been able to find a pattern yet.

Well, Kingston was cheap :)  (Yeah, now we know why.)  We use 128 MB cards
because they weren't all that expensive.  We dropped base.tgz, etc.tgz,
man.tgz and a few packages from pkgsrc + our own config stuff on the card.
Sure, we could fit it all in 16 MB or so, but we saw no point in doing that.
With a 128 MB card, it will be easier to upgrade NetBSD (just extract the
new versions of the tarballs) without the need to manually tune the system
for minimum FLASH consumption.

I think Sami's going to do something like that soon :)
