Apparently the qemu guys have been poking at this:

http://lists.gnu.org/archive/html/qemu-devel/2011-04/msg02307.html
http://lists.gnu.org/archive/html/qemu-devel/2010-09/msg01225.html

Honestly, they're the people you need to talk to.

I'm open to kernel .config changes for the armv6l target.  Currently the
board localization in sources/targets/armv6l is:

LINUX_CONFIG="

# Processor config

CONFIG_CPU_V6=y
CONFIG_MMU=y
CONFIG_ARM_THUMB=y
CONFIG_AEABI=y
CONFIG_VFP=y

# Versatile board

CONFIG_ARCH_VERSATILE_PB=y
CONFIG_PCI_LEGACY=y
CONFIG_SERIAL_NONSTANDARD=y
CONFIG_SERIAL_AMBA_PL011=y
CONFIG_SERIAL_AMBA_PL011_CONSOLE=y
CONFIG_RTC_DRV_PL031=y
CONFIG_SCSI_SYM53C8XX_2=y
CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=0
CONFIG_SCSI_SYM53C8XX_MMIO=y
"

If you see any symbols that should be removed from or added to that...

Agreed, that's why I put the wrapper scripts there.

Have you tried the:

  ./dev-environment.sh 2>/dev/null

workaround yet?  What's only going to discard error messages
_from_qemu_, which seems like what you want...
