Depending on when you downloaded it, you may not have the latest mainline
which is at:

http://git.denx.de/?p=u-boot.git;a=summary

Nevertheless, you will have the latest x86 patches

Hmm, I don't think U-Boot is what your after. There are a few problems you
will be faced with:
 - There is no ACPI support (no power management)
 - No System Management Mode (SMM) support
 - No chipset support (No RAM initialisation)
 - No Cache-As-RAM init code

Unless you have at least these covered, you will brick your board if you
try to flash U-Boot. You might instead take a look at coreboot

Ah, I now see that the patch I thought had been applied has not :(

You will need this patch:
