I am not sure whether you are
correct about the PLL being initialized (I don't know

have attached the dmesg output from 2.6.10 compiled with your patch
Thanks for the testing and dmesg. From the dmesg, we can see 1st adapter: pll_ctl[57][D] => PLL initialized by the firmware 2nd adapter: pll_ctl[57][D] => PLL initialized by the firmware 3rd adapter: pll_ctl[58][4D] => PLL uninitialized 4th adapter: pll_ctl[58][4D] => PLL uninitialized
So, the firmware on the pdc20269 only initialize the 1st and 2nd adapters. PLL of adapter 3/4 are left uninitialized by the firmware.
The pdc202xx_new driver relies on the firmware to initialize the PLL. That's why adapter 3/4 won't work.
I have yet to test ATAPI devices on it.
With 2.6.10 + pdc20269, there is a known problem on ATAPI DMA. Please use 2.6.11 to test ATAPI.
