Oh. That's tlp0, not tlc0, for anyone that's really paying attention.

I ended up, for now at least, installing the 2.1-RC3 sets. Didn't really 
work very well, but I got a kernel that seems to support the skc/sk 
DGE-530T (Marvell 88E1011 chipset), at least to the point where it will 
light up the link LED on the hub, even if it doesn't light up its own 
LEDs in any way. Very odd behaviour there - I think I'll try another card...

But the file system isn't really quite right; no big surprise, I guess, 
since I used the 3.0 floppies. Would really like to find the correct 
sets to install...
