Maby not the greatest comfort, but I've had a Dell
2650 with the Perc3-controller working for weeks. I
installed rt3 (troubleticket-system) which needed
Mysql (or postgresql). I installed Mysql 4.0 and
haven't had problems with it. I increased the amount
of RAM than Mysql can utilize, but that's about it.

All installed from /usr/ports using portinstall.

FreeBSD 5.2.1, 2 GB RAM, dual Xeon @ 2.4 Ghz. Other
than enabling -O2 and CPUTYPE=i686 in /etc/make.conf
and make a customized kernel with amr in my kernel,
everything else is pretty much default.

I never touched HTT in BIOS nor using sysctl, that's
working out of the box.

/etc/make.conf:
CPUTYPE=i686
CFLAGS= -O2 -pipe -funroll-loops -fno-strict-aliasing
COPTFLAGS= -O2 -pipe -funroll-loops
...
etc. etc. etc.

/usr/src/sys/i386/conf/DELL2650:
machine     i386
cpu            I686_CPU
ident          DELL
options      SCHED_4BSD              #4BSD scheduler
options      SMP                     # Symmetric
MultiProcessor Kernel
device        apic
device        amr             # AMI MegaRAID
device        bge             # Broadcom BCM570xx
Gigabit Ethernet
