I may not fully understand your problem, but wouldn't FAI just detect the
availability of UEFI (via /sys/)? Everything else should be handled by the
DHCP/TFTP server side (which is only closely related to FAI).
Whether there's a 64-bit system installed depends on the NFSROOT assigned.
But since you want to talk to the 32-bit UEFI first, perhaps the following
years-old snippet from my dhcpd.conf may point you in some direction:
...
## https://www.syslinux.org/wiki/index.php?title=PXELINUX#UEFI
if substring(option vendor-class-identifier, 0, 20) =
"PXEClient:Arch:0" {
filename "pxelinux.0";
}
if substring(option vendor-class-identifier, 0, 20) =
"PXEClient:Arch:6" {
filename "syslinux32.efi";
}
if substring(option vendor-class-identifier, 0, 20) =
"PXEClient:Arch:7" {
filename "syslinux64.efi";
}
if substring(option vendor-class-identifier, 0, 20) =
"PXEClient:Arch:9" {
filename "syslinux64.efi";
}
...
You may have to look for ldlinux.* and syslinux*.* files in various subtrees
provided by the syslinux-common package, and copy them into your TFTP tree.
