Invalid symbol table on NetBSD boot

[Grégoire Sutre]

Hi,

When booting a NetBSD 5.0 (i386 or amd64) kernel with knetbsd (as per
docs/grub.cfg), the first message displayed by the NetBSD kernel is:

[ Kernel symbol table invalid! ]

and after boot, the device /dev/ksyms is not configured.  The same
problem occurs with multiboot instead of knetbsd (for i386 only, as the
NetBSD kernel does not support multiboot on amd64).

However, the system after boot seems to work fine.  This issue
apparently only affects the in-kernel debugger.

A similar problem is mentioned in the archives of the mailing list [1]. 
 I tried to adapt the patch given in [1] to the current trunk, but with 
no luck.  And the patch focuses on multiboot, so I guess it would not 
solve the problem with knetbsd.  This stuff is way above my head 
anyway...  But I'd happy to help by testing :-)

Thanks for your help,

Grégoire
