This is rather interesting, from sager's development department.

here is the answer from our Engineering Dept. please check!
I hope this is a good answer for you!
Thanks,
In response to your question regarding the availability of the MR9800 in
Sager laptops, the short answer is the company is still evaluating
whether to use the MR9800 in its products.
With the introduction of the New PCI-Express form factor in 2003, Sager
has concentrated its design in that direction instead of video module
design based on the AGP Bus. As of now we are still on schedule with
our plans to release the first series of laptops based on PCI-Express by
the end of fourth quarter 2004. Also, the MR9800 is not exactly
pin-to-pin compatible and has increased power consumption demands over
previous versions. For those reasons, no final decision has been made
on offering the MR9800. As more information becomes available, we will
send out announcements to our licensed resellers
