For anyone else looking for a WRT54G or GS that can run third party (Linux) firmware upgrades, here is a shortlist way of telling which version of the router is in the box without even having to open it. (Of course, the VxWorks versions are not compatable with third party firmware,)

*** Linksys router versions ***

Known serial numbers (first four characters) vs versions:
CDF0 = WRT54G v1.0
CDF1 = WRT54G v1.0
CDF2 = WRT54G v1.1
CDF3 = WRT54G v1.1
CDF5 = WRT54G v2.0
CDF7 = WRT54G v2.2
CDF8 = WRT54G v3.0
CDF9 = WRT54G v3.1
CDFA = WRT54G v4.0
CDFB = WRT54G v5.0 (runs VxWorks, not Linux)

CGN0 = WRT54GS v1.0
CGN1 = WRT54GS v1.0
CGN2 = WRT54GS v1.1
CGN3 = WRT54GS v2.0
CGN4 = WRT54GS v2.1
CGN5 = WRT54GS v3.0
CGN6 = WRT54GS v4.0
CGN7 = WRT54GS V5.0 (runs VxWorks, not Linux)

SJH0 = WTR54GS v1.0

CL7A = WRT54GL V1.0

The MAC address and Serial Number are on a small barcode tag just below the main UPC on the bottom of the box.
