I believe the largest test that's been run was the old OSDL CGL workgroup ... they went up to 4096. However, LUN support depends on the driver and HBA parameters as well (some choose to have arbitrary limits). So, firstly, if the inquiry strings appear (as in you see a scsiX:X:X:64 and above in dmesg) then I'd look at udev issues. If the inquiry strings don't appear, it's probably a device or driver programmed limit.
