The failure you showed can only occur with a kernel with CONFIG_HIGHMEM
enabled.  In any case, highmem should now work on 2.6.

Re the 3ware problems:
Could you build a 2.6 dom0 kernel with #define TW_DEBUG added before
the dprintk macro gets defined around line 248 (the file is
linux-2.6.7-xen0/drivers/scsi/3w-xxxx.h), like this:
#define TW_DEBUG 1
#ifdef TW_DEBUG
#define dprintk(msg...) printk(msg)
#else
#define dprintk(msg...) do { } while(0)
#endif

Also, does the boot get to the point where it prints a line like:
Found a 3ware Storage Controller...
I couldn't find a mail from you which included dmesg output of a failed
2.6 boot, please include all the output from Xen and from dom0 when
you boot with TW_DEBUG enabled.
