DCON doesn't assert correct status during resume

while the system is running, freezing/unfreezing the dcon works fine.
when the system is resuming, the dcon doesn't assert the correct status (0x01) on its two status lines at the time of the first scanline interrupt after the DCON unload happens. a workaround has been installed in the driver to treat this case specially, otherwise we will wait and timeout after a second, looking for the "right" interrupt. the missing status signal is troubling, however.
(missing status assertion (of DCONSTAT0) verified using o'scope.)
