I didn't know BCM4321s identifying as 14e4:4321 are that seldom - the
mini-PCI card in my D-Link DSL-2741B (which is a BCM6358) also does

Same here, dma is a no go (I have to use pio).

Same for the one in my BCM6358 - perhaps SPROM-less devices default to
their chip-id as the PCI device id (just wildly guessing)? I also have
a second BCM6358 with a BCM4322; same there (no SPROM, DMA doesn't
work, and it identifies as 14e4:4322).


P.S: I also get these 0x0F90 clear failures ;)
