Take a look at appendix D « Administering Oracle Database on Solaris » in the « Oracle Database Administrator's Reference 11g Release 2 (11.2) for Linux and UNIX-Based Operating Systems ». It's stated how and why Oracle uses Intimate Shared Memory on Solaris 10. (I'd give you the URL, but the documentation site appears to be down at the moment).

If you "create pfile=''/tmp/pfile.txt'' from spfile;" can you see if the above parameters are set? If so, that might explain things.
