Attaching piixide device before pdcsata device

Hi all,

I'm faced with a problem that's proving quite difficult to solve. My system is populated with 8 internal SATA drives. 4 drives connected to the on-board SATA connectors. 4 drives connected to a Promise TX4 300. The issue here is, at startup, the Promise card is detected first and hence the drives on this card are mapped as wd0, wd1, wd2 and wd3 onto the pdcsata device. Thereafter, the on-board drives are detected and mapped as wd4, wd5, wd6 and wd7 onto the piixide devices. Is it possible to have the order re-arranged such that the on-board drives are detected and mapped first as wd0, wd1, wd2 and wd3?

The relevant portions of the dmesg file are listed below:

ppb0 at pci0 dev 30 function 0: Intel 82801BA Hub-PCI Bridge (rev. 0xe1)
pci1 at ppb0 bus 1
pci1: i/o space, memory space enabled

wd6 at atabus5 drive 0: <WDC WD1000FYPS-01ZKB0>
wd7 at atabus5 drive 1: <WDC WD1000FYPS-01ZKB0>

Any assistance with this would be greatly appreciated.
