HP EliteBook 2530p
HP apparently decided my 2510p was cursed and replaced it with a 2530p which arrived earlier this week. A bit of playing later and it all seems pretty happy. Backlight control works fine, though you'll need hal-info git to get the hotkeys working out of the box. Sound needs alsa from 2.6.30 or for snd_hda_intel to be loaded with the "model=laptop" parameter. Suspend seems to work out of the box. Hotkeys and rfkill work with hp-wmi. The webcam is supported by the uvcvideo driver. The wwan modem needs qcserial from 2.6.30 and a tool for loading the firmware. It's happy to boot from EFI which probably saves a second or so of boot time. Wireless is iwl5100 and supported by the drivers from Intel. Video is GM45 and worked fine without any tweaking. I've no idea if the modem is supported or not, and I haven't tested the fingerprint reader yet. Grub was slightly unhappy about the idea of an EFI system partition that wasn't declared in a GPT, but that was a two line diff.
I've backported code to rawhide where necessary, so F11 should be released with full support for the hardware. It's quite a nice machine, and seems more solid than the 2510p - I'll see how it's going in a year or so.
