[U-Boot] Bad Linux ARM zImage magic

Due to this patch: 0001-omap3_beagle-uEnv.txt-bootz-n-fixes.patch, u-boot for my beagleboard seems to need always a zImage. Up to now, I used uImage just fine. Questions: -          Can I convert vmLinux or uImage in to the required zImage? -          Is it possible to use bitbake (I’m using the Angstrom 3.28 kernel) to create a zImage instead of uImage? -          Can I just replace the part "loaduimagefat=fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} zImage\0" With "loaduimagefat=fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} uImage\0"   In omap3_beagle.h to get the previously working behaviour?
