.... I am currently using HP nx6310; after the initial problem with npx freezing when MULTIPROCESSOR is on, I an reasonably happy with it. The wireless (wpi) works (but not with wpa_supplicant for me), the Ethernet (bce) as well (I just have to disconnect the power supply for a moment when rebooting from XP). The only minor gripe is that I could not get the audio (azalia) work through the speakers, but it works fine through the headphones; also the SATA controller has to be set to compatibility mode for NetBSD, which is weird, as the native mode is supported by both OpenBSD-current and FreeBSD-current. I haven't yet tried seriously suspend/resume. The graphics - Intel 945 - works in VESA mode under XFree86, but I installed Xorg 6.9 from pkgsrc and this is now served by the I810 driver, so it's OK. Otherwise it looks quite well built; one may not like the 15" screen with 1024x768 native resolution. though (or, maybe, like - depends on one's eyes...).
As far as OpenBSD-current is concerned, I just booted the installation CD and collected the dmesg (posted earlier in current-users@), but it looked OK at this stage. I tried at one stage FreeBSD6.2 Beta1, but did not get the wireless and the azalia working straight from the CD (I found an OSS audio driver, but did not want to deal with bits from outside of it; as I have another ath wireless card, which worked, I did not bother to look at the wpi one).
