Firefox and other non-IE browsers(again)

I've seen many posts about lack of non-IE browser compatibility, but still no solution (MyIEtab ISN'T a solution). The CSS fix solves it partially, but not completely, and the fix of putting a rectangle in the top is just a joke.

Currently my reports can't be browsed by Firefox and other Mac browsers, and that's going to be a stopper for further using of SSRS in the future in my company. I was expecting SP2 to do something about this, but it hasn't solved anything. I'm sure it's a very easy patch for MS, but by maintaining this (artificial?) limitation they're going to make us move from SSRS and even the full SQL Server stack for future projects.

Any other *real* solution, other than CSS and big rectangle in the top of the report?This could be a huge problem for my client also.

I wonder how many customers Microsoft lost over this. I know it is free and all (with Sql Server), but doesn't do much for customer confidence.
