I don't think either one does, I've tried the two above that were against 2.4.21
and even manually correcting the rejects, 2.4.23 will not compile.  Also it
looks like the content of those patches has largley been moved into 2.4.23
source, you can choose IGP support natively in 2.4.23. 

However in my case i have
ATI Technologies Inc Radeon IGP 340M
PCI: 00:00:0: chip 1002,cbb2 card 0000,0000 rev 02 class 06,00,00 hdr 00
in an hp pavilion ze5300 laptop.

agpgart would not detect this with the stock 2.4.23 kernel and IGP enabled, I
don't know if it truly doesn't support it yet or cbb2 identifier got overlooked.
 I *seemed* to have gotten around this by simply replacing "cab2" with "cbb2" in
these files.

drivers/char/agp/agp.h
drivers/pci/pci.ids

I did this because I noticed looking at the patches that the cbb2 is for RS_200M
and cab2 is for RS200, and those are both in the original pci.ids RS200/RS200M
AGP Bridge [IGP 340M]. I'm just guessing that the same code could be used for
both, and perhaps the cbb2 just didn't make it in.

In anycase everything seems to be working great at the moment,  I'm now
compiling the XFree snap shop with IGP patch.

Currently I'm using rpm based X 4.3 with an IGP patch and radeon driver, created
per the instructions here

http://www.rexursive.com/articles/linuxonhpze4201.html

Which has been working fine for sometime, but glxinfo shows with my current
config dri is not working, thus i'm compiling the x snapshot with igp patch.

Hope that's of some help, if you have cbb2 340M as well, only do what I did at
your own risk of course :)
