The real fix is > to fix the driver to not require 2048 byte mbufs. I've looked at differences between pdq (DEC FDDI Controller) and idt(4). It seems pdq does the right thing by specifying that it wants its buffers to be 2048 bytes, using MCLGET() to ask for the cluster after the mbuf, then using busdma to allocate the 2048 byte buffer.
