Well, it would work with any arch, _if_ there was a way to sync the streaming pci dma buffers before giving them back to hardware. Last time I checked there was no pci_dma api call to achieve this on all platforms. For X86 however it's trivial due to cache coherency.
The guy is used with X86 notebooks only - unless whoever owns the controller design decides to make some CardBus PC-Card for people with notebooks lacking IrDA-support.

Valid point, yes.

Thanks, second this.
