I don't think so. The 2742 EISA two channel controller works with ahc0
and looks at both channels. You don't need a second ahc entry in your kernel.
I don't have anything on the second channel in the moment, hence the
empty second probe:

ahc0: <Adaptec 274X SCSI host adapter> at 0x4c00-0x4cff irq 11 on eisa0 slot 4
ahc0: 274x Twin Channel, A SCSI Id=7, B SCSI Id=7, 4 SCBs
ahc0 waiting for scsi devices to settle
(ahc0:0:0): "FUJITSU M2694ES-512 811F" type 0 fixed SCSI 2
sd0(ahc0:0:0): Direct-Access 1033MB (2117025 512 byte sectors)
(ahc0:1:0): "TOSHIBA MK538FB 6030" type 0 fixed SCSI 2
sd1(ahc0:1:0): Direct-Access 1172MB (2400302 512 byte sectors)
ahc0 waiting for scsi devices to settle
