Please help! I am going to buy an LG laptop LE503LSZ:

LE50 Intel Pentium M 740 1.73 533FSB 2048K Processor
ATI RS400MD chipset, Radeon x200M 128 shared graphic card
15'' XGA 1024X768 TFT LCD
2X256 DDRII533 SO-DIMM
60Gb 4200 RPM HDD, DVD super multi writer, SD card, PCMCIA
4 USB, 1394A, VGA, S-video TV out, 10/100 LAN, 56K Modem,
Wireless LAN 802.11b/g, wireless dual hexa band antenna, XP pro.

It looks nice, but I have doubts about the chipset: ATI RS400MD
Somewhere I read that it is very close to Intel 915PM, but I could not
find information neither about the chipset nor about the model LE503LSZ,
even on the LG website.
What worries me is how this chipset will work with Linux (Fedora Core 4).
Can you say something about it?
Perhaps I should say that I do not care about wireless and modem, but graphics
and sound are important.

Many thanks in advance!
