[ACPI] /proc/acpi doesn't show up

[BBNS <bbn...@ms...>]

Hello,
    I'm working with my Presario 17XL364 laptop.
    I have patched acpi-20020503-2.4.18.diff.gz with kernel-2.4.18
    and now there is no /proc/acpi/. :(
    (but the acpi modules still can be installed...very strange.)
    From reading the messages in the mailing list, it seems like I get the buggy BIOS.
    How could I patch it?
    I'm a new hand and it would be nice  if someone can teach me.:)
    
Very thanks

Tim Tsai
    
    p.S : Here is my dmesg:
