I'd guess not, if it still works. I'd guess that there were minor differences in the 154xA microcode, and that you have a very early version. Be warned, however, that there's a bug in the driver that hits many 154xAs: it writes a block of 16 0xff characters at not-quite-random places in large transfers (typically after 32 kB). You might like to check that with non-critical data first. It would be interesting to know whether it happens to your version.
