Odd that it sees "log_buf_len=", but not the "console=" that's defined right
ahead of it:

The linked kernel *looks* correct (x86_64 here):

Do I smell some bad pointer math?  Yeap:
DEBUG: sizeof(obs_kernel_param): 24 (0x18)

obsolete_checksetup(): line: ro
obsolete_checksetup(): checking: nosmp(5) @ ffffffff80593510
obsolete_checksetup(): checking: <NULL>(1) @ ffffffff80593528

p++ moved the pointer sizeof(obs_kernel_param) ahead, but that's 8 bytes
short.
