I was translating this into Spanish and had a good chance to look this over a bit. I corrected a few typos and added a little extra guide-xml formatting for the sake of improved clarity. I hope you all agree ;)
Created attachment 32391 [details, diff] diffs
Created attachment 32394 [details, diff] gentoo-sparc-faq.xml.diff Previous patch was not properly done. It was reversed and not done using the right options. Please use diff -Nu old.xml new.xml Besides, resulting doc was not valid. Please use xmllint --noout --valid new.xml before posting. I made the doc valid and applied coding style. I also removed the comment and link to blameseemant.tk. I found it rather unprofessional and some readers might even find it offensive (tombstone). The diff is almost twice the size of the doc but I attached it for the record. May the translators forgive such a long diff for so little content change.
Committed.
