The syslog buffer is normally allocated in the boot loader and not relocated.
The feature doesn't have any restrictions as to when a panic happens. There is,
however, the problem that it doesn't work on some hardware. The current theory
for that is that on such a machine the RAM is reset during boot (whether on
purpose or by accident (temporarily unpowered) is unclear).
