What a wonderful config you've got ! I do only have a poor 360CSE
with 4Mb of RAM and 340Mb of disk space. I am running DOS/Windows
on a small compressed paritition (40MB) and the left room is used
by Linux.

I have also been disappointed by the Ethernet Card. A few weeks ago, I
purchased a Xircom PCMCIA Card. I thought it was supported by the Linux
PCMCIA package from David Hinds, but apparently, it is not. There seems to
be a problem with Xircom not publishing the technical information about their
cards. Checking with the customer service, it seems that we have to buy a
developpers kit ! The card does, of course, run under r DOS/Windows but it's
useless for me. I think I'd better buy a simple (less efficient) D-Link card
which it supported by both operating systems.

Can't help you on this point

OK, this is a classical problem with Thinkpads, I do have the same problem.
The trick is as follow to avoid rebooting:
On exit from X11, you must press the Fn+F7 key and you'll get the text screen
again.

Do not have enough pixels on my display to help you here !!!

No on-board modem on my Thinkpad but just a PCMCIA one (which seems OK : supported !)
