5 Hyperthreading is detected on an SMP system with APIC-IO.
7 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).
11 Works perfectly with the Broadcom bge(4) driver.
15 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.
19 Still need ACPI to work.
23 should work fine with snd_hda. Haven't tested yet though.
27 looking forward to trying to get DRI to work.
