OK, here it is:

With -fvisibility=hidden
kde-cvs@broadway kdelibs $ readelf -a 
~/kdecvs/temp-build/kdelibs/kded/.libs/libkdeinit_kded.so | grep 
TI10KDEDModule
000198e4  00012401 R_386_32          00019980   _ZTI10KDEDModule
00019944  00012401 R_386_32          00019980   _ZTI10KDEDModule
   292: 00019980    32 OBJECT  WEAK   DEFAULT   14 _ZTI10KDEDModule
  1138: 00019980    32 OBJECT  WEAK   DEFAULT   14 _ZTI10KDEDModule

With -fvisibility=default
kde-cvs@broadway kdelibs $ readelf -a ~/kde/lib/libkdeinit_kded.so | grep 
TI10KDEDModule
00015804  00012401 R_386_32          000158a0   _ZTI10KDEDModule
00015864  00012401 R_386_32          000158a0   _ZTI10KDEDModule
   292: 000158a0    32 OBJECT  WEAK   DEFAULT   14 _ZTI10KDEDModule
  1092: 000158a0    32 OBJECT  WEAK   DEFAULT   14 _ZTI10KDEDModule

So they appear to both have the same visibility now.  So again, I probably 
screwed up somewhere along the way the first time I tried it. :(
