Have you tried downgrading to 7.2? I know the Tecras worked pretty well with the 6.x series. Are you running the stock Red Hat kernel, or did you compile your own? Typically, Red Hat does a lot of QA work on the kernels, so if you are compiling your own that could be part of the problem.
You might try running X unaccelereated, but renicing the X process. Do, as root: renice -20 WHATEVERTHEPIDOFXHAPPENSTOBE You might also renice your window manager and/or your panel.
