For Intel servers, there is some help in 2.4. It is now included within the OpenIPMI driver. It saves the panic info into a firmware log. See http://sourceforge.net/projects/openipmi/ and http://panicsel.sf.net (more info, plus a 'showsel' utility to view the firmware log).
The parameter to save this isn't turned on by default in OpenIPMI, but it is there in 2.4 kernels (CONFIG_IPMI_PANIC_EVENT).

On the other hand, if like me you use a text-based console almost exclusively, then the best course of action is probably to buy a real serial terminal, (or several :-) ), and configure one of them as the console. Then you can basically ignore the VGA display completely.
