Do not require a digit after the known prefix. This makes console detection work with various serial drivers, which use device names like ttymxc%d or ttyAPP%d. ---
An (even more lenient) alternative solution would be to try opening any device passed as console=X as /dev/X as a last resort when all prefix matches fail. Checking that the file is a chardev might make sense then? The latter should also allow using console=null to disable the console completely (which I consider a desirable feature, although it is currently not working for the Linux kernel console either [1]). Please let me know which solution you prefer, so I can update my patch accordingly.
