I don't think that is relevant.  SYM1 and SYM2 both only drive 53c8xx
chips (and newer, 53c1010, etc).  SYM1 didn't drive some of the nearly
53c810 chips (iirc), and you needed ncr53c8xx.c to drive those.

There was no linux driver for 53c720 before parisc.  Now we drive 53c720
with a modified ncr53c8xx.  So, something like my B180 with a bluefish
card uses:

CONFIG_SCSI_LASI700 (James driver) for 53c710 (cdrom)
CONFIG_SCSI_ZALON (modified ncr53c8xx) for 53c720 on blusfish
CONFIG_SCSI_SYM53C8XX (SYMV1) for 53c8?? main disk interface

So, in theory, chnaging to CONFIG_SCSI_SYM53C8XX_2 for all configs
shouldn't upset anyone.  SYM1 and SYM2 both only drive PCI chips, so
that makes the change irrelevant to earlier boxes anyway.
