Ok, so you made me nervous. I tried it on several machines:

[tcurrie at hamster tmp]$ touch TEST
[tcurrie at hamster tmp]$ touch TeST
[tcurrie at hamster tmp]$ touch test
[tcurrie at hamster tmp]$ ls
test  TeST  TEST
[tcurrie at hamster tmp]$ rm te*
[tcurrie at hamster tmp]$ ls
TeST  TEST
[tcurrie at hamster tmp]$

...works fine on RedHat 9.0...

tcurrie at nakedpc:~/tmp$ touch test
tcurrie at nakedpc:~/tmp$ ls
TEST  TeST  test
tcurrie at nakedpc:~/tmp$ rm te*
tcurrie at nakedpc:~/tmp$ ls
TEST  TeST
tcurrie at nakedpc:~/tmp$

...Slackware 9.0 has no problem with it, and last but not least,

[tcurrie at localhost tmp]$ touch test
[tcurrie at localhost tmp]$ ls
test  TeST  TEST
[tcurrie at localhost tmp]$ rm te*
[tcurrie at localhost tmp]$ ls
TeST  TEST
[tcurrie at localhost tmp]$

...a fresh install of Fedora Core 1 has no problem with it. Are you sure 
you're not doing something strange here? What is the underlying 
filesystem (ext2, ext3, reiserfs)? How are you accessing this? NFS? Samba?
