@ArchiMark

Error you got is pretty straightforward, fix the menu item. There are plenty of examples how it should be done mentioned already, it's not that complicated. If you can't make it, please at least post the contents of the file so we can actually help, but do know that the inability to resolve problem like this will probably mean a very hard learning curve ahead with Arch.

@no-one in particular

I may sound like an *******, but U-Boot has been discussed already in this thread many times, even though this is not a thread for U-Boot. I understand that it can be a pain to set up, but this thread will not be of any help to anyone, nor constructive in any way, if its filled up by 20 pages of U-Boot errors mostly caused by inability to read instructions. So, the U-Boot thread has very detailed instructions, and in my book, it has every bit of info you may need to have in setting it up. This thread has many useful posts and even examples how it should be done. If someone feels this is not enough, both we and maemo.org have a wiki, feel free to make a documentation of the matter everyone can understand.
