  The disagreement between helioseismology and a recent downward revision of
solar abundances has resulted in a controversy about the true neon abundance of
the Sun and other stars. We investigated XMM-Newton and Chandra high-resolution
X-ray spectra of weakly and moderately active stars (log L_x/L_bol = -5...-7)
and determined their coronal Ne/O abundance ratio by using two linear
combinations of strong emission lines as well as a global-fitting method. The
sample stars show a correlation between their Ne/O ratio and stellar activity
in the sense that stars with a higher activity level show a higher Ne/O ratio.
We find that the Ne/O ratio decreases in our sample from values of Ne/O~0.4
down to Ne/O~0.2, suggesting that ratios similar to 'classical' solar values
are rather common for low activity stars. A significantly enhanced neon
abundance as the solution to the solar modeling problem seems unlikely. We find
no indications of a peculiar position of the Sun among other stars.
