Installed system
Hyperthreading is detected on an SMP system with APIC-IO.
I'm still in the process of getting a useful system. ACPI doesn't work, and with out it, the wireless livelocks and doesn't work either. Last tested IRC's polachok's newacpi kernel (2009-10-26).
Wired network
Works perfectly with the Broadcom bge(4) driver.
Wireless
I removed the Intel card and put in an Atheros 5424 series which is known to work well in Dragonfly using ath(4). It gets a little bit hotter than the default Intel card.
To get it to work I had to boot once with the sysctl hw.pci.mcfg=1 After that it worked perfectly.
Power Management
Still need ACPI to work.
Sound
should work fine with snd_hda. Haven't tested yet though.
Graphics
looking forward to trying to get DRI to work.
