Just for your information, I have patched football A17 rom, it's available in his thread with CF support. ;)
Updating the first post to have it look nicer.
First I want to thank
football for being the first to try and succeed in building a new rom for an axim device.
Here some screenshots of the rom (from his websire 4pda).



The rom is build on WM5 aku 3.5.2 with x51v drivers and utilities, it doesn't contain any extra software.

Original russian Thread
The original thread is the main post contains the patched rom.
There is also an english thread @ xda, but it still doesn't include the patched rom at the time I'm writing those lines.
Flashing a ROM via SD is a potentialy dangerous and will invalidate your axim warranty.
You will be responsible for it if you do it, this is neither my responsability neither aximsite's responsibility.
Although, I spent time on this rom during these last two weeks, I didn't spent so much time to really use it.
I spent all the time trying to understand how it was build in order to try to fix the CF issue.
So don't ask me too many question on it.

Update:
I have added modification on the fooball A17 rom, it has now
SDHC support,
message windows are centered, It fixes the battery indicator issue, and the missing recording icon in notes. It also has the colorado fix embedded and has transcriber and messenger. and I also changed:
HKEY_LOCAL_MACHINE\System\ObjectStore\RegistryType to 0, to be in file based registry.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Navigation\"4-Way Nav"=0 (PIE button scrolling navigation)
HKEY_LOCAL_MACHINE\System\StorageManager\FATFS\Cac heSize=4096
HKEY_LOCAL_MACHINE\System\StorageManager\FATFS\Ena bleCache=0x1(1)
HKEY_LOCAL_MACHINE\System\StorageManager\Filters\f sreplxfilt\ReplStoreCacheSize=4096
HKEY_LOCAL_MACHINE\System\GDI\GLYPHCACHE\limit=327 68
HKEY_LOCAL_MACHINE\Comm\Tcpip\Parms\TcpWindowSize= 98304
These settings are supposed to increase performance, you'll get these values from sktools. However as they increase performance by using more RAM, I have changed the
pagepool value to 5 Mo. By doing so you will get more than 32 Mo at soft reset.
The default value to page pool for x51v Rom is 8 Mo. You can modify pagepool value by using the
PPeditor tool from Paveld, then you'll also need his
CRC cal tool.
I have called this modified rom M17, it's available
here.
