[syslinux] pxelinux and 2.6.9 kernel parameters

I have successfully and easily loaded RHEL4 onto my machine. The dmesg
shows the following:
BIOS provided physical memory map:
BIOS-88: 00000000000 - 000000009F000 (usable)
BIOS-88: 00000100000 - 0000001000000 (usable)
This shows several points:
The BIOS only supports the E88 memory call.
The BIOS reports 16Mb memory only.
The memory map is lacking detail that an E820 call would have provided.
The kernel must have the correct memmap parameter passed to ensure all
available memory is used.
How does this effect pxelinux? My current version is 2.11. Will a later
version give me a different/better result? Where does the kernel get
loaded in memory? Does it start at 1M and go up from there? What about
the initrd; where does it go?
