I just bought a DisplayLink adapter that's compatible. Compiling a new kernel 
with device udl brings this error:

--------------------------------------------------------------
>>> stage 3.2: building everything
--------------------------------------------------------------
linking kernel.debug
udl.o: In function `udl_attach':
/usr/src/sys/dev/usb/video/udl.c:(.text+0xa07): undefined reference to 
`edid_parse'
/usr/src/sys/dev/usb/video/udl.c:(.text+0xa0f): undefined reference to

*** [kernel.debug] Error code 1

Thanks,
