It may have taken longer than anyone expected but there is now a procedure for rooting the HTC Dream that has the Rogers E911 patch applied. As you remember this patch placed a perfected SPL onto the device that blocked the rooting procedures in use at the time.

Go check out the link above to find the complete instructions and download links needed to break that nasty SPL from the E911 update and get CyanogenMod installed onto your Dream.
