Yes, with some driver hackery. In zoran_device.c, line 429, you'll see:
if (format->palette != VIDEO_PALETTE_YUV422)
reg |= ZR36057_VFESPFR_LittleEndian;
Change that to:
reg |= ZR36057_VFESPFR_LittleEndian;
I.e., remove the "if" part, and all RGB formats will be BGR now. Please
remember that overlay will be buggered. It's much easier to change your
conversion function to handle RGB instead of BGR, since the driver *is*
doing the right thing here.

Run v4l-conf first.
