Have you verified that udev is creating the /dev/mapper nodes correctly? On my 2.6.15 system (FC4), /dev/[VG name] is just a directory with the following entries: 

lrwxrwxrwx  1 root root 31 May  1 23:13 LogVol00 -> /dev/mapper/VolGroup00-LogVol00                                                                             
lrwxrwxrwx  1 root root 31 May  1 23:13 LogVol01 -> /dev/mapper/VolGroup00-LogVol01 


You're also seeing the move to /dev/mapper as 2.6 uses LVM2, which utilized device-mapper.
