This doesn't really solve your problem but...

In Sybase you decide on sort-order and case when you install/configure the dataserver (not a particular database). This configuration then applies to the entire dataserver, including the system tables. So if your application data needs to be case sensitive, then the table names will be case sensitive too.

At least this is how I understand the issue, I'm sure mpeppler can explain it in more detail :)
