Bug description:
  I have 3 PCs with different Ubuntu versions 10.04, 10.10 and 11.04.
  In all of these firefox4, chromium, epiphany and konqueror are pretty fast, except on Narwhal when visiting web pages with javascript.
  I noticed that on 11.04:

  1) it happens on all js-capable browsers
  2) pages without js are rendered alright
  3) when js is disabled on firefox4 it seems to speed up some not all, though, e.g. it does for cnews.ru, but not for launchpad.net (which never loads)
  4) w3m-img,elinks,lynx are fast and load those pages in questions alright
  5)none of these problems exist on 10.04 or 10.10 with web browsers of the same versions
  6) it is an Ubuntu 11.04 only issue, does not happen on older version of Ubuntu
  7) does not seem to be an ipv4/ipv6 issue, since on firefox I set ipv6.disable to true
  On the affected machine (as well as on the others) I got a custom kernel installed.
