Considering the Linux PCMCIA HOWTO from 2003 talks about booting using
initrd it would appear capable of a solution.
I have a machine with a BIOS which cannot boot from USB, a situation not
too dissimilar from yours. So I constructed a new Wheezy initrd containing
the USB drivers and used it and the kernel to make an iso file. The file
was put in /boot and /etc/grub.d/40_custom had
menuentry "usbBOOT" {
set isofile="/boot/usb-boot.iso"
loopback loop $isofile
linux (loop)/boot/vmlinuz-3.1.0-1-686-pae root=LABEL=USBSTICK
initrd (loop)/boot/initrd.img-3.1.0-1-686-pae
}
added to it. update-grub was ran.
Selecting usbBOOT boots straight into the OS on USBTICK.
