Compatible Laptops.

[Naoya Sugioka]

I'm using Dell M4400.

At first, it has a problem when acpi is loaded. Kerenl shows a panic
message with default config,
so I had to look for a workaround.
I read acpi(4) manpage, then append loader.conf

debug.acpi.disabled="cmbat"

it was necessary to boot. But still boot strap has stopped with ACPI
module when following message
is displayed.

>  isa_probe_children: probing PnP devices

After I put some debug prints around it, I found ACPICA needs to be updated.

1. go, accept the license,  then download latest 102310 from www.acpica.org
2. replace sys/contrib/dev/acpica-unix with latest
3. apply necessary changes on  sys/dev/acpica5.
    I attach my wild patch for a reference - not sure it is right
modification though : )
4. compile the kernel, install.

Now my Dell laptop got booted with no trouble (hw.acpi_io_enable=0 is
required for SMP though)

So far, even if your laptop is not booted with default kernel, you can
still have fun to find out a
workaround.  Now I'm playing with wifi (iwn0).

 Enjoy!
