Something actually was changed at some point perhaps?
On i386, kernelname is dug out of bootinfo and copied
(in assembler).
On alpha:
p = getenv("kernelname");
if (p)
strncpy(kernelname, p, sizeof(kernelname) - 1);
Did the loader used to set kernelname as an environment variable?
At any rate, this should be easy enough to fix (doing so right now).
