My Devcon 2008 contribution: port for Philips GoGear HDD1630 (PP5022-based). Current status is that the bootloader works to load Rockbox, but dual boot does not work: it freezes after decrypting the OF. When Rockbox boots, it freezes somewhere between showing the logo and the main menu. And there's no driver for the touchpad. So lots of work left.
