2.6.24-rc1 (2.6.23 plus the patch for rc1, plus the patch you mentioned on
the 25th:
   http://marc.info/?l=linux-kernel&m=119332492222601&q=raw

With basically just using 'defconfig' (I turned on VDE, but otherwise touched
nothing in menuconfig).

I used:
swingline(10)% gcc -v
Reading specs from /usr/lib/gcc/i386-redhat-linux/3.4.6/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=i386-redhat-linux
Thread model: posix
gcc version 3.4.6 20060404 (Red Hat 3.4.6-8)

running:
make linux ARCH=um CFLAGS=-I/scratch/epaulson/vde/include

I get:
