[X-Wrt] X-WRT with kamikaze -where to download from?

Have an older WRT54G v3 Linksys router, and luci lua, the openwrt web interface gui, runs extremely slow , if at all.
Looking for an X-WRT made with OpenWrt Kamikaze (v7, v8) or White Russian.
Unfortunately, after 2 days searching with Google, only X-WRT or berlioz.de shows up, but there are no download files are available.
There must be some other places where these once popular downloads are available!
Any suggestion where can I find them ?
Thanks for any input !
