booting ipaq h5555 from CompactFlash microdrive

Hello handhelds/h5400 list,

I am attempting to boot Familiar v0.8.4 from a 4GB Hitachi Microdrive (CompactFlash) on an iPAQ h5555 with a CompactFlash sleeve (not PCMCIA), following the steps at:

http://www.handhelds.org/moin/moin.cgi/BootingLinuxFromCF

I am unfortunately running into all sorts of issues though, so I am hoping the lists can help me out.  My disk partitioning is slightly different than the wiki's. I have a 64 MB vfat partition, a 960 MB linux swap, and the other 3 GB as a ext2 filesystem.  I am making the assumption that the h5500 series is mostly compatible with the h5400 series, the main difference being memory size (I believe).  I suppose a good first question would be, is bootldr known to work with CompactFlash sleeves?  Most references I've found online are to PCMCIA sleeves.  Is there a difference in modules/drivers between these two types of sleeves?

The most common problem I am running into is the "filename too long" error.  There was a quick fix posted online that failed for me (remounting the vfat partition as msdos and recopying initrd, param and zimage in).  There was also a suggestion that bootldr cannot handle large vfat partitions (> 32 MB), but the post was years old.  Is this still the case?

Here is what happens using the linked initrd and zimages from the wiki:
