Ok, so here's how my testing on my eMachines M6805 laptop with fresh Haiku builds is going so far. I will also be testing it soon with a Gateway MX7118, but not until SATA is working in Haiku, check back for those results soon.
Processor Mobile AMD Athlon 64 3000+ 1800MHz 1MB L2 - Detected and works
Northbridge Via K8T800, Southbridge Via VT8235 - Detected and works
Memory: 1GB+256Mb SODIMMS work fine.
Hard Drive Hitachi TravelStar 5K80 60GB 5400RPM (Mine is upgraded to a TravelStar 100GB 7200RPM) - Detected and works fine
DVD Drive Lite-On DVD/CD+RW (untested for DVDs, and CD Burning)
Card Reader Neodio ND3260 8in1 Reader (untested but doubtful on this until USB mass storage is done)
Video ATI Mobility Radeon 9600 Series - ATI RV350 NP - Detected and works (accelerated too)
Display Samsung LTN154X1 15.4" WXGA - just works
Ethernet Via Rhine II - Detected and works
Wireless Broadcom BCM94306 802.11g (no wireless in Haiku that I can see so far)
Modem Smart Link v.92 56K winmodem (untested, no need for modem with broadband...)
Audio Realtek ALC250 - Tested and works
Cardbus ENE CB1410 (untested)
Firewire Via VT6306 (Firewire is being worked on still)
Touchpad Synaptics - Tested and just works
So it's already better supported than it ever was on BeOS. The firewire did work on BeOS so I suspect that when they get firewire working in Haiku that will work on this model as well.
