Seaboard still works perfectly after this patch (or should; I assume Allen tested it!). The only issue is that you can't use SPI; the assumption being that you store the BCT/bootloader in eMMC rather than SPI and hence have no need to use SPI. SPI can be tested on other Tegra20 board designs, such as TrimSlice (or perhaps Kaen/Aebl if they're still around!)
