Well it appears to be a different issue in daper. I got suspend to ram
working by using this workaround advice:
One thing about sleep: vbetool needs to save and restore your video
state in order to have working video on resume. Currently, on Macbooks
this is broken. This is caused by a mistake: the vbesave init script
comes before the acpi init script. This means that laptop-detect will
report to vbesave that you are not on a laptop and vbesave will not
save your vbestate. Matthew Garrett is working on a fix, but in the
mean time a workaround is to edit /usr/sbin/laptop-detect and insert
a line 'exit 0' right after the #!/bin/sh (always report that we're
a laptop).
