This driver is enabled. The problem might be that this version your
rtl8139 is not(yet) supported. There is a patch that might fix your
problem.
Is there some debian hacker willing to build a GNU Mach package with
Alfred's patches included? I will have another look at my autoconf
patch, to see if I can fix the current problems without changing that
much. Marcus told me that adding extra drivers to gnumach-1-branch
(upstream CVS) is not a problem. This is something that is not hard
to do, so I will do that soon.

It works just like linux, although GNU Mach can't load modules. Use
the right arguments for configure (--enable-rtl8139, for example) and
run make.

This is partially true. With kernel components the person who wrote
this meant: `components that normally run in kernelspace'. (Well, that
is what I think ;))
An example is ext2fs, it runs in userspace. You can implement extra
filesystems (translators) as user and run them as a user. Better
examples are `ftpfs' and `pfinet' (the TCP/IP stack).
In the far(?) future L4 will be used as microkernel. It does not have
userspace drivers, etc.
