What do you think about or do you know about compatibility?
It seem to be interesting for me?

I thought so! My wife bought one of these and I put 10.5.3 on it. We are pleased with the result, but here is what works and doesn't:

Working:
- Keyboard, trackpad
- SD slot
- Audio output and internal speakers
- Internal camera
- Both CPU cores
- Wifi using replacement Broadcom card ordered on eBay (BCM-4311)
- Bluetooth
- Internal Ethernet
- USB
- Graphics with full QE Acceleration
- Internal mic with hardware modification (hacked in a Logitech USB headset board + microphone, connecting to internal ExpressCard slot USB port.


Not working:
- Sleep (sleeping messes up Wifi and other devices, requiring reboot)
- External USB DVD drive not recognized by DVD Player (requires VLC to play DVDs)
- Battery meter sometimes works
- Internal Wifi which shipped with the laptop (required replacement, see above)

The following are the steps I followed. I would appreciate input from anyone who knows how to correct the sleep issue and/or get the battery meter fully working as that is all that separates us from a 100% perfect install.

1. Install Kalyway 10.5.2 with default (sleep_kernel)
- select NVinjectGO
- do not select other options, other than "thirds applications"
- remember to include pacifist and kexthelper b7 (or download these later). Kexthelper greatly simplifies kext installation

2. Install Kalyway 10.5.3 ComboUpdate, but do not install the kernel update

3. Install AppleACPIPlatform.kext and Chun Nan's ApplePS2Controller.kext using kexthelper b7

4. Replace internal wireless card (under keyboard to the right) with Broadcom BCM 4311 card. Airport now works.

5. Install NVinstaller52, select "go (mobile/laptop)"

6. Install the USB Fix Installer and reboot. USB attach/removal should now be working.

7. Install Power management fix installer to get battery meter display. Does not properly detect AC power.

Hope this helps someone else out!

Some other notes:

- I tested other kernels from the 10.5.2 DVD and could not get others to work
- 10.5.4 Combo update upgrade trashed the system; I was then discouraged enough not to try the 10.5.4 delta update
- Sleep is currently messing up both wired and wireless network connections and possibly other things. I have simply disabled sleep for the time being.
- the LG P300 seems to ship with garbage RAM. If after 1-2 months of operation you get panics, look at this first. It cost me a fully working installation of OSX because I did fsck before checking that the RAM was okay.

Good luck!
