2.6.2-rc in BK: Oops loading parport_pc.

[Matthias Andree]

Loading the parport_pc modules crashes in 2.6.2-rc; I have recently done
a "bk pull" and enabled some PNP options, among them ISA PNP.

Find attached the gzipped config and a decoded oops. Does ksymoops 2.4
(using 2.4.8) understand Kernel 2.6 kallsyms? Doesn't seem so. 2.4.9
segfaults for me, haven't yet figured why.
