It might be possible with care.  I doubt if solaris will be able to
handle Linux file systems.  In Linux, you need to configure the kernel
with
CONFIG_UFS_FS=y
but I seem to recall that if you do this and mount such a file system,
if you don't use it read-only, your results will be unpleasant.  Others
will have more current information.

Sun hardware.  Slice 3 (/dev/[sh]da3) must be the entire disk, for
example:
   Device Flag    Start       End    Blocks   Id  System
/dev/sdb1             0        22     31779   83  Linux native
/dev/sdb2  u         22       698    976482   82  Linux swap
/dev/sdb3  u          0     24620  35563590    5  Whole disk
/dev/sdb4           698     24620  34555329   83  Linux native

(second disk on one of my systems.)
