Just uploaded mine too. 4GB 3" 16:9 (non touchscreen) Veho Quinque RK2706 player here. Firmware version is 2.20 and includes support for microSDHC.
Download here:
Rockchip firmware: Veho Quinque 3.0" 16:9 4GB v2.20.
NB: I haven't yet worked out how to get this back onto my player - can anyone please point me in the direction of a method?
