All this was nothing -- after hitting send, I realised that I'd
hosed ~all~ my networking capability. I figured out where my
mistake was, but not ~what~ the correct entries should be. In
the end, I just removed all the settings I'd made & got back to
just being able to ping either way, inside & outside, as well as
ftp between the 'puters, but I can't get the W98 beyond the Linux
box.

Sure:
/sbin/route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref
Use Iface

Oops. Wish I could help, but while I've heard mention of bttv
modules, I've no idea what the do....
