2.4.21-ben2 and acard aec6280m (CONFIG_AEC62XX_TUNING)

[dorian <dorian@cybercity.ch>]

i got 2.4.20-ben8 to work with my aec6280m by setting

CONFIG_BLK_DEV_AEC62XX=y
CONFIG_AEC62XX_TUNING=y

however, in 2.4.21-ben2, the latter option seems to have disapeared and 
i get (again) lots of

hdX: dma_timer_expiry: dma status == 0x24
hdX: lost interrupt
hdX: dma_intr: bad DMA status (dma_stat=30)
hdX: dma_intr: status=0x50 { DriveReady SeekComplete }

whenever a harddisk that is connected to the acard is accessed.
has anyone succeeded in putting this card to work with a 2.4.21 kernel?

btw, many thanks to benjamin herrenschmidt at this point. your work for 
the linux/ppc port is greatly appreciated!

tia,
