This breaks for me with:
ERROR: "dma_supported" [drivers/ssb/ssb.ko] undefined! ERROR: "dma_set_mask" [drivers/scsi/qla2xxx/qla2xxx.ko] undefined! ERROR: "dma_set_mask" [drivers/scsi/aic7xxx/aic7xxx.ko] undefined!

They just need to be exported like on x86_64.
Cheers, Mark.
Subject: [PATCH] x86: export dma_supported() and dma_set_mask() on i386
dma_supported() and dma_set_mask() were previously inlined, but are now moved to pci-dma_32.c.
Since they're used by various drivers, they need to be exported.
