Does the intel-driver not accalerate bitmask blits?

I tuned a java-benchmark to make better use of hardware-accaleration
(uses now bitmasks instead of argb images), and saw some improvement,
but not in the range I expected.
I used oprofile to see whats going on and got that:
85483 51.5340 libfb.so libfb.so (no symbols)
36338 21.9066 java (no symbols)
10595 6.3873 no-vmlinux no-vmlinux (no symbols)
10064 6.0671 Xorg Xorg (no symbols)
This profile shows that a lot of time is spent inside of libfb,
however I really wonder why so much time is spent there.
Does the intel driver simply not accalerate bitmasked blits?
Thank you in advance, lg Clemens
