As you say, for completeness:

SCSI subsystem driver Revision: 1.00
parport0: PC-style at 0x378 [PCSPP]
parport0: irq 7 detected
imm: Version 2.04 (for Linux 2.4.0)
imm: Found device at ID 6, Attempting to use EPP 32 bit
imm: Found device at ID 6, Attempting to use SPP
imm: Communication established at 0x378 with ID 6 using SPP
scsi0 : Iomega VPI2 (imm) interface
  Vendor: IOMEGA    Model: ZIP 100           Rev: P.05
  Type:   Direct-Access                      ANSI SCSI revision: 02
Detected scsi removable disk sda at scsi0, channel 0, id 6, lun 0
SCSI device sda: 196608 512-byte hdwr sectors (101 MB)
sda: Write Protect is off
 sda: sda4

As I noted in a previous posting to the list my Communication type is
misdetected as SPP when it really is EPP. The 101 MB size looks fishy
also as it usually reads 96 MB IIRC.
