kern/62438: viapm patch for VT8235

[FUJIMOTO Kou]

Everytime when I enable acpi function I get the same result,
while the patch works without any problem when I disable acpi
(either on boot time or in kernel config).

This workaround is reported on FreeBSD-users-jp ML (in Japanese):
http://home.jp.freebsd.org/cgi-bin/showmail/FreeBSD-users-jp/78394

In the message above, Ito-san suggests 'isab' (PCI-ISA bridge) is
not probed with the patch and acpi enabled.
