I played arround with an HA-Cluster under RedHat 2 years ago, and from that 
what I remember, the backend machines (real servers) do not necessarily have to 
run under Linux, they can also run under another OS. So you would just have to 
setup the 2 (or 1) load-balancing routers under Linux and the servers would 
still run under Solaris.

If you haven't done it yet....
You might also try to install the php-accelerator on your webservers 
(http://www.php-accelerator.co.uk/) it should also reduce the load and speed up 
the service. 
And if you have money...
try the following: http://www.horde.org/zend (and help the horde project :-))

BTW: We run IMP (~11k users) on a single SUN Fire 280 2x 900Mhz and 4GB RAM and 
have no real preformance problem (may be your users use it more than ours)...
