The main problem seems to be that X cannot find a screen. And the RADEON
driver doesn't show up in the Xorg log.
I think the root cause is that the system doesn't know which one to choose.
=46rom the Xorg log:

What I would try is build Xorg without HAL, and add
Option "AutoAddDevices" "off"
to the ServerLayout section of your Xorg.conf.
Add two Device sections to your Xorg.conf using the data from pciconf;

=46rom your dmesg, it seems that the HD 4200 is connected to the monitor;

Then write a Screen section containing one of the monitors. Most listing for
the CQ62 list it as using a HD 4200, and it seems to be the one used at boo=
t,
so I'd try that first.
Section "Monitor0"
VendorName "built-in"
Identifier "Monitor0"
EndSection
If you know the pysical size of the monitor, add a =E2=80=9CDisplaySize wi=
dth height=E2=80=9D
line to the Monitor0 section. That will help calculate the horizontal and
vertical pitch.
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1366 x 768"
EndSubSection
EndSection
Xorg will load the necessary modules when it starts.

You cannot use the new vt(4) driver on 10.0-RELEASE. It is only available on
10-STABLE. This means that you cannot switch from X back to the sc console.
That is not supported with kernel modesetting. You will either have to do
without or upgrade to 10-STABLE. I'm on r269090 using a Radeon X 1650 Pro a=
nd
it works fine.
After upgrading to 10-STABLE, use kldstat to see which modules are loaded by
Xorg, and add them to /boot/loader.conf. Then you can enable vt. An excerpt
=66rom my /boot/loader.conf:
# Kernel modules
radeonkms_load=3D"YES"
drm2_load=3D"YES"
iicbus_load=3D"YES"
iic_load=3D"YES"
iicbb_load=3D"YES"
radeonkmsfw_R520_cp_load=3D"YES"
# Use the new vt driver.
kern.vty=3Dvt
N.B: Do *not* use the `radeonkmsfw_R520_cp_load=3D"YES"` line. It's not the
correct firmware for your chip!
Hope this helps...
