lkml, James,

When building 2.5.26 with CONFIG_VT=n and CONFIG_SYSRQ=y, the resulting
kernel can't be linked:

drivers/built-in.o: In function `sysrq_handle_unraw':
drivers/built-in.o(.text+0x14694): undefined reference to `fg_console'
drivers/built-in.o(.text+0x14698): undefined reference to `kbd_table'

The following is a work-around for this problem.  There is probably
a cleaner solution to this.
