If the Debian 5 system is a server, I would remote mount my home 
directory on my workstation with the hardware graphics driver, and run 
chimera locally.  Or you might be able to copy libGL.so from your 
workstation to a directory in your home directory on the server and set 
the LD_LIBRARY_PATH environment variable to that directory.

If the Debian 5 system is supposed to be a workstation, I would be very 
tempted to reboot it with a Ubuntu Live CD and when done, reboot it back 
to Debian 5, or maybe the administrators would be willing to make it a 
dual-boot system.  Your idea, of compiling a software-only version of 
Mesa, should work if you set the LD_LIBRARY_PATH environment variable 
appropriately.

In the LD_LIBRARY_PATH cases above you would need to start chimera from 
the command line after setting up the environment or start chimera after 
editing the CHIMERA/bin/chimera shell script.

     Hope this helps,

     Greg
