Just got my SGSII yesterday... my m4a tags are fine! Not sure what's happening with yours D:
EDIT: I was totally wrong, the artist didn't show up. Luckily I had like one album in m4a format, so I changed it to mp3 and everything's fine now! Just missing a few album arts here and there, but I think that's more a Winamp problem than a problem with the SGSII
