As in, the drac STONITH scripts don't work with it. The name drac5 kind 
of suggests that, too.

but no 6? ;-)

Gotcha. I saw in your other email that it could work with IPMI too. 
http://support.dell.com/support/edocs/software/smdrac3/idrac/idrac10mono/en/ug/html/racugc2.htm 
suggests it supports IPMI.

I guess I was hoping to find someone who's actually used this particular 
device with Pacemaker, but we'll be trialling and erroring soon enough. ;)
