Sounds like the bge(4) driver might work.  Take a look at
"pciconfig -lv" 
to identify the chip and PCI vendor id.  Try adding that
information to 
src/sys/dev/bge/if_bge.c::bge_devs[] and subsequent chip
revision arrays.  
It's easiest to build a kernel w/o device bge and loading
bge from 
modules.  This way you can cd to src/sys/modules/bge and
"make load; 
#test; make unload; #change source; #repeat" until it
works.

Thanks to Max Laier's help, the ether device is now working
with the 'bge'
driver.  Here is a patch that makes it work.  I just
recompiled the
kernel afterwards and it comes up.

PS: the T105 is now $399 but includes 1GB RAM and 2x160GB
disk,
    in addition to the dual-core 1.8GHz Opteron and DVD
reader.

(Is there a better way to do this? sorry for the CC's,
wasn't sure which
was appropriate for getting this into the tree.)
