It's not possible to set environment varibles for arbitrary processes from
the pre-boot environment. But you can get the job done by making up kernel
command line options. For example:

title Boot from /usr/src/linux/.../bzImage
kernel (hd0,0)/usr/src/linux/arch/i386/boot/bzImage src vga=5 idebus=66

grep src /proc/cmdline >/dev/null && echo "Booted from /usr/src."
