I saw a similar problem with 2.6.9, but the errors I got are:

  CC drivers/ide/ppc/pmac.o
drivers/ide/ppc/pmac.c: In function `pmac_ide_macio_attach':
drivers/ide/ppc/pmac.c:1351: warning: passing arg 1 of `iounmap' discards qualifiers from pointer target type
drivers/ide/ppc/pmac.c: In function `pmac_ide_dma_read':
drivers/ide/ppc/pmac.c:1942: error: `ide_dma_intr' undeclared (first use in this function)
drivers/ide/ppc/pmac.c:1942: error: (Each undeclared identifier is reported only once
drivers/ide/ppc/pmac.c:1942: error: for each function it appears in.)
drivers/ide/ppc/pmac.c: In function `pmac_ide_dma_write':
drivers/ide/ppc/pmac.c:1973: error: `ide_dma_intr' undeclared (first use in this function)
drivers/ide/ppc/pmac.c: In function `pmac_ide_setup_dma':
drivers/ide/ppc/pmac.c:2148: error: `__ide_dma_off_quietly' undeclared (first use in this function)

drivers/ide/ppc/pmac.c:2159: error: `__ide_dma_timeout' undeclared (first use in this function)

I turned on most of the PCI IDE stuff in the configuration, and these
errors went away. I still got a warning (from gcc-3.3.4):

drivers/ide/ppc/pmac.c: In function `pmac_ide_macio_attach':
drivers/ide/ppc/pmac.c:1351: warning: passing arg 1 of `iounmap' discards qualifiers from pointer target type

For your stuff, I see that kauai_pio_timings and IDE_WAKEUP_DELAY are
defined if CONFIG_BLK_DEV_IDEDMA_PMAC is defined; so turn that on in
the configuration, and see if the problems go away.
