Yes, there's a line in /boot/grub/menu.lst towards the top.  Usually it
reads Default=0 (or something similar--writing this from a BSD machine
so can't check the exact syntax.)

0 is the first entry, 1, the second, etc. 

Just change the default to read 1 if you want to boot the older kernel,
which should be the second in the list of possible entries.

Assuming (which I'm only doing because you mentioned Linpus) that it's
the Aspire One, it's odd that wired isn't working.  The only
distribution that gave me trouble with wired out of the box was CentOS,
due to an older version of the kernel driver.  (There were workarounds,
detailed in my article on the CentOS wiki.)

Hrrm, I don't think I've tried wired and NM with it though.  

Also, just for what it's worth (I don't know about NM) the 2.6.27
kernels typically refer to that card as wlan0 while the earlier kernels
that use the MadWifi driver will call it ath0.

I've only had my wireless automatically set as eth1 with Intel 2100
(although it's probably true for the 2200 as well) card.   Again, this
is leaving NM out of the equation though, coming from the BSDs I'm just
more comfortable doing it by hand.
