FreeBSD on the LinuxCertified LC2210D Laptop
intention of this
document is to provide information required to run FreeBSD 5.4 or
greater on the LC2210D laptop.
environments due to its exceptional stability and performance,
FreeBSD also performs very well on the desktop and laptop. A wide
variety of desktop environments, window managers, and productivity
oriented software are available to the FreeBSD user through the ports
system, and recent versions of FreeBSD boast excellent support for
the many different pieces of hardware found on modern laptops.
Because of the combination of superior performance, stability,
software choices, and hardware support, FreeBSD is a natural choice
for many laptop users.

found on the laptop, the snd_ich module needs to be loaded. In
order for resume to work properly, the vesa module requires patching
and must be loaded prior to resuming normal operation from a
suspended state. The “acpi” kernel module is also needed, but is
automatically loaded in a default installation. If your system is not
properly loading the ACPI module, append “acpi_load=”YES”” to
the loader.conf example file below. After modifying loader.conf,
please reboot your system to make sure that all modules load properly
and you have not made any typographical errors. If you wish to skip
the reboot, 'kldload snd_ich' and 'kldload vesa' will install the
modules for you.

fully functional suspend to ram support: A small patch to the VESA
driver in order to re enable the LCD backlight after a resume. Upon
resume, the system will come up normally, however the screen will
remain black. While the screen may not be viewable, the keyboard is
indeed functional and you may safely shut down your laptop if
necessary. In order to get around the backlight problem, we must load
the modified “vesa” module in loader.conf (or by hand using
