I don't think this is deliberate. I suspect it's just a BIOS bug: the 
BIOS authors probably just never considered that anyody would ever want 
to boot from SD, so didn't include the feature. You could try making a 
bug report to IBM.

Incidentally, I suspect that the hardware doesn't connect the internal 
SD/CF reader as a USB device. Once booted into Linux via another means, 
does the internal reader show up in lsusb?

May I ask why you particularly want to boot from SD?
