That kind of list shouldn't be made just for one OS/platform. We have SharpROM, SharpROM based, pdaXrom, OpenZaurus (for Zauruses), OpenSimpad, Familiar 0.8 is coming... So if a HW list be created then it should be easy expandable for other systems then just pdaXrom.
For example: I plan to buy Pretec WiFi CF Card so info which distributions supports it and via which driver will be good for me. If I will get info "it run under pdaXrom" then info is partially unuseful as I won't know which driver it use under pdaXrom.
