Further to the topic of installing Linux on the WRT54 series of Linksys devices; Linksys has a relatively new device, the WRTSL54GS. Basically its the old WRT54GS PLUS a USB port!

And yes there is a OpenWRT available for it.

No more storage limitations; just plug a USB hard drive in or other USB type storage and you're off !

For those wanting to run Asterisk on it you now have room for voicemail.
