This is not a Nehemiah but an Esther CPU which seems to support nopl (I
checked with a small program). Futhermore it seems the whole nopl issue
got fixed in the kernel:
 http://lkml.org/lkml/2008/9/5/374
(b74b06c5f6612a72298f37baa65460a59c26ca67)
but unfortunately not for 2.6.26:
 $ git-name-rev b74b06c5f6612a72298f37baa65460a59c26ca67
 b74b06c5f6612a72298f37baa65460a59c26ca67 tags/v2.6.27-rc6~4^2~10
(and it doesn't seem to be in any of the 2.6.26.X series).

So to me it seems the workaround can be removed:
 * removed for VIA Ester altogeher
 * removed vor VIA Nehemiah once we ship 2.6.27
