Correct Shibby firmware for a WRT54G-RG router

Hi, I'm currently running plain Tomato 1.28 on my Linksys WRT54G-RG router. I believe the WRT54G-RG is identical to the WRT54G-TM in terms of specs. The RG was for Rogers while the TM was for T-Mobile. Anyway, the WRT54G-RG has 8MB of Flash and 32MB of RAM and I'm just wondering what the correct version of the Shibby firmware I should be flashing.

Thanks!
