Bogomips is definitely not a benchmark, it should give us some idea.
I believe its the same processor in Buffalo Linkstation LS-XHL, which has a bogomips of 1200---a very impressive score for ARM, while Atom 230 gets 3200.
Really, no need to wait for OpenWRT support, this should be capable of running a FULL debian by chroot to SD card or USB disk, or simply feed it with Optware.
