The 3.0 is suppose to be released today, or perhaps tomorrow.

For 3.1 kernel we have this long list of features and bug-fixes that we are 
to ask Linus to pick up:

 - VGA text support. Since Xen is the first payload on the bootloader it gets 
   screen information - now with this patch we can copy it from the hypervisor
   and enjoy 80x25 old-school text output.
 - MODULE_ALIAS on backends so that udev will autoload them.
 - tmem driver to shuffle file-system and swap pages between guests as 
   Runtime it is disabled unless 'tmem' parameter is supplied.
 - self balloon driver to decrease memory in the guest and make the swap pages
   be shuffled by tmem to be compressed/shared/etc. Runtime wise it is disabled
   by default (use 'selfballooning' to enable it and make sure you have a swap 
 - pciback backend. It complements the xen pci front driver which together
   allow guests to have host's PCI devices.
 - cleaning up the Xen PCI glue code.
 - Fix section mismatch in Xen PCI HVM driver (xen-pci-platform).
 - Fixes to the generic pagetable to compute precisely how many pages we need.
 - blkback can now provide completion latency that follows the hardware's 
 - PVonHVM blkfront naming fixes.
 - Xen MMU debugfs has gotten a facelift - now it uses the tracing API.

Please tell me or Jeremy if we are missing anything or need to chase something
