The ata driver doesn't want to place nice & share IRQs, and by the time the xl driver gets a chance to alloc irq10 the ata driver has reserved it totally. The following should fix it (beware, its against a slightly less-than-current version of ata-all.c; should it fail to apply, just replace the RF_SHAREABLE arguments to bus_alloc_resource with RF_SHAREABLE | RF_ACTIVE in ata_pciattach(). S=F8ren's told me that he'll be fixing this in his next commit.
