On http://wiki.openwrt.org/OpenWrtDocs/Har … c233791a33 it says some WRT54GS v4.0 have 4MB/16MB, and some have 8MB/32MB.
Is it possible to tell which model you have from the box serial number? Eg does anyone have a confirmed 8MB/32MB WRT54GS v4.0 they could tell us the serial # of? would also be useful to know if higher serial #'s have 4/16.
