That seems to do the Right Thing(tm)

[GCC 4.1.1 20060816 (Red Hat 4.1.1-17)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import yum
>>> y = yum.YumBase()
>>> y.doGenericSetup(cache=1)
>>> f = y.pkgSack.searchNevra(name='kernel')[0]
>>> print f.provides
[('kernel(arch_i386_kernel_acpi)', 'EQ', ('0',
'c12529424b24e79b680d1d902fa237feb66fd643', None)),
('kernel(net_irda_ircomm)', 'EQ', ('0',
'4e3f32809cbc77ad37f94c965234cee4a88714ed', None)),
('kernel(drivers_usb_atm)', 'EQ', ('0',
'5383458d106c9f5d30b2419d2b7677413acc4a72', None)),
('kernel(drivers_pnp)', 'EQ', ('0',
'd561469c83435a81c108639edb336baf2a369661', None)),
.
.
.
>>> print f.providesnames
['kernel(arch_i386_kernel_acpi)', 'kernel(net_irda_ircomm)',
'kernel(drivers_usb_atm)', 'kernel(drivers_pnp)',
'kernel(arch_i386_kernel_cpu_mcheck)', 'kernel(drivers_net_phy)',
'kernel(drivers_media_video_cx88)', 'kernel(lib)',
'kernel(sound_isa_cs423x)',
.
.
.
>>> f.version
'2.6.17'
>>> f.release
'1.2597.fc6'

Which is definitely from the cache as I don't have that kernel
installed.

I confirmed that the testmod output still gives similar to the above with
missing provides.
