Still happens on my FreeBSD 4.{6,7} console servers @work, where we use 
RocketPorts pretty widely. (We even have some old RP ISA cards floating 
around that are still in use)

WARNING: driver rp should register devices with make_dev() (dev_t = 
"#rp/0x10014")

I did hear that a new rp driver (nrp?) had been written/committed in -CURRENT 
sometime late last year, and apparently made it in 5.0-RELEASE, but hadn't 
been back-ported to -STABLE yet (but patches have been floating around in 
the archives).  I haven't had a chance to test it yet, although one of the 
things the new driver apparently fixes is you are now able to use more than 
one PCI card in a box.  (we have some installs where we need a second PCI 
card to drive a third/fourth "pod", where this would be useful)

That's what we do here... (tangled in a web of cat-5 and silver satin cables 
at the moment)
