PhotoCD & UNIX? - PCD to TIFF?

We have some National Aerial Photography Program slides scanned onto a
Kodak PhotoCD (multisession), and want to import them into our UNIX
GIS system (GRASS). My questions:

1) Can a PhotoCD be mounted on a UNIX system? If so, how?
  (I tried the standard "mount -r /dev/sr0 /cdrom", but no luck
  -- is it a specific file system type that needs to be noted?)
  I can attach the CD to either a SPARCclassic or an IPX.

2) If # 1 is possible, can I just copy the *.pcd files I want to my
  SPARCclassic and use as they are, or do I need to run "dos2unix"
  on them?

3) Is there a PCD to TIFF converter around, perhaps as a new addition
  to the PBMplus toolkit? (I'd like a straight, hi-resolution
  conversion of the PCD format to TIFF)

4) Is there a UNIX (SunOS 4.1.3 or Sol 2.2) viewer of Kodak
  PhotoCD's, or a program that views/reads/converts the
  *.pcd format?

Some background:

Each *.pcd image is > 4M , and Corel (Draw/PhotoPaint) can not import at
the highest resolution (on a 486/66 w/8M RAM). This was my initial plan --
to use Corel(something) to convert to TIFF.

Any help sent our way will be GREATLY appreciated!!
