wine security-patched kernel ?

[traxtopel]

Trying to run an application using wine on fedora core 0.94 results in
..
err:virtual:map_image Standard load address for a Win32 program
(0x00400000) not available - security-patched kernel ?
/usr/bin/wine-freelance: could not load 'C:\lotus\flg\f32main.exe' as
Win32 binary

"security-patched kernel ?"

What has changed in the redhat kernel which has caused this problem?
