It's not a problem with the driver.  The card has two MACs in a single
package and the PXE bootrom on the card allows booting from the first
interface only.  As the test system was running (semi-)diskless, I could
only test using wm0.  Since I had no problem with wm0, I would expect
not to have problems with wm1 either.

I arranged a kernel config to force root on wm1 ("boot -a" can't be used
as the USB keyboard doesn't work at the "root device:" prompt).  I boot
over wm0 or the machine's built-in bge0 and switch the cable to wm1
while the kernel is initializing.

Stress testing building packages has proceeded without incident.
