DD-WRT v23 SP1 RC1 firmware is now available (as of May 8) on the
dd-wrt website. It's found under the "dd-wrt.v23 SP1" directory on the
downloads section of their website.
There are ALOT of fixes and updates (over 200, looking at the
changelog) since the original v23.

If you're willing to take a little risk, you may want to give this a
test now, before SP1 goes final and you find a feature you need,
doesn't work... Make sure you read the hwsupport.txt file and the WIKI
before you load the firmware.
