Following up to myself for the benefit of the archives - I can confirm that
the PERC4e in the PE1850 works perfectly with amr(4) under 6.0.  I've been
using the sysutils/megarc port for managing the adapter from FreeBSD.  It
has a truly awful user interface but allows you to do everything that the
BIOS setup program does, so far as I can tell.

For monitoring we're relying on the email alerts from the DRAC/4 management
card also in the machine, which turn out to work very well.  We actually
had a disk failure on the machine already (one of the drives had apparently
worked itself a bit loose in transit and decided to power itself off a few
days after I put the machine in the rack).  The DRAC sent out an email when
the drive "died", it auto-rebuilt when shoved back into the slot properly,
then another email from the DRAC when the rebuild was complete.

I'm looking forward to the amr(4) performance improvements in 6.1 and being
able to run the Linux megmgr tool (I think this is the one with the same
user interface as the BIOS setup program).
